Clays are materials consisting of clay minerals and non-clay minerals. Some applications allow to use raw clay others require to separate clay minerals from non-clay minerals. Clay mineral fraction is considered to be a nanofraction. Description and characterization of 3 different Latvian clay nanosized minerals from 3 different geological periods (clay Liepa from Devonian period, clay Vadakste from Triassic period and clay Apriki from Quaternary period) are summarized. The main mineral in these clays is illite, however the presence of kaolinite is observed and its quantity depends on geologic

Abstract:
In the mines of Guanajuato, Mexico, when miners drill and dynamite for metallic ore, they dislodge other substances. Among these are elements and compounds known as “minerals,” sold and collected in their own right as scientific specimens or aesthetic collectibles. These minerals often fetch thousands of dollars at mineral shows and collector showrooms in Tucson, Arizona and other mineral collecting hubs. In this process, minerals move from byproducts and even waste to highly valued commodities in their own right.

Abstract:
AbstractDietary iron (Fe) deficiency affects 14% of the world population with significant health impacts. Biofortification is the process of increasing the density of vitamins and minerals in a crop, through conventional breeding, biotechnology approaches, or agronomic practices. This process has recently been shown to successfully alleviate micronutrient deficiency for populations with limited access to diverse diets in several countries (https://www.harvestplus.org/). The Fe breeding target in the HarvestPlus program was set based on average rice consumption to fulfil 30% of the Estimated Average Requirement of Fe in women and children. In this review, we present the reported transgenic approaches to increase grain Fe. Insertion of a single or multiple genes encoding iron storage protein, metal transporter, or enzyme involved in the biosynthesis of metal chelator in the rice genome was shown to be a viable approach to significantly increase grain-Fe density. The most successful approach to reach the Fe breeding target was by overexpression of multiple genes. Despite this success, a significant effort of 8–10 years needs to be dedicated from the proof of concept to varietal release. This includes large-scale plant transformation, event selection, collection of data for premarket safety assurance, securing biosafety permits for consumption and propagation, and collection of data for variety registration.

Abstract:
This chapter shows how southwest Missouri miners maintained their pursuit of market opportunities as industrial capitalism foreclosed those opportunities nationally in the 1870s. They did this by mining and marketing zinc, once a worthless by-product of lead mining. Their zinc mining created a profitable new market that partially freed working miners from the control of smelting companies. At a time of national economic depression, this development made the mining region famous as a poor man’s camp where capital-poor but hard-working men could work on their own account, as independent owner-operator miners, and possibly make considerable sums of money. When smelting companies looked to take control of zinc, some miners turned to antimonopoly politics, but most miners responded as before, by searching for mineral discoveries as prospectors on undeveloped land in Missouri and now in Kansas. By seeking new opportunities to enter the market again as independent producers rather than fight the smelting companies, as workers forming unions elsewhere did, these miners kept alive their faith in capitalism and risk-taking work.

Full text
Abstract:
The chemical elements in soil minerals occur typically as charged species arranged in spatial configurations held together by ionic bonds. Ionic bonds involve atoms that retain their unique “electron clouds” and, therefore, they are weaker than covalent bonds, which involve significant mixing of the electron clouds of the bonding atoms, leading to the electron sharing that makes covalent bonds stronger. However, ionic and covalent bonds are idealizations that real chemical bonds only approximate. A real chemical bond shows some degree of ionic character, which maintains the electronic identity of the bonding partners, and some degree of electron sharing, which blurs their electronic identity. The Si—O bond, for example, is said to be an even partition between ionic and covalent character, and the Al—O bond is thought to be about 40% covalent and 60% ionic. Aluminum, however, is exceptional. Almost all the metal–oxygen bonds that occur in soil minerals are ionic. For example, Mg—O and Ca—O bonds are considered to be 75% to 80% ionic whereas Na—O and K—O bonds are 80% to 85% ionic. Covalence thus plays a minor role in determining the atomic structures of soil minerals, aside from the important feature that Si—O bonds, being 50% covalent, impart mineral resistance to weathering, as discussed in Section 1.3. Given this perspective on bonding, the two most important properties of the chemical elements in soil minerals should be their ionic valence and radius. Valence is the ratio of the electric charge on an ionic species to the charge on the proton. Ionic radius is a less direct concept, because the radius of a single ion cannot be measured. Accordingly, ionic radius is a defined quantity based on the following three assumptions: (1) the radius of the bivalent oxygen ion (O2-)in all minerals is 0.140 nm, (2) the sum of radii of the cation and anion participating in a chemical bond equals the measured interatomic distance between the two, and (3) the ionic radius has the same value in all mineral structures containing an ion with a given coordination number (CN).

Abstract:
Poultry production, health and wellbeing are highly dependent upon formulation of balanced rations in terms of energy, protein, and micronutrients (vitamins and minerals). Among all, minerals are required in fewer quantities, but they are very important to maintain the productivity in poultry. Minerals present in the feeds are less bioavailable and additional supplementation is obligatory to meet the physiological demands of poultry. Conventionally, minerals are supplemented as inorganic salts, which are less absorbed and, thus, a major proportion is excreted to the surroundings creating environment issues. Nano-minerals and organic mineral chelates are other alternative to be used as livestock and poultry feed supplements. Though organic minerals are more bioavailable than inorganic salts, their high cost limits its use. In contrast, nano-minerals are relatively easy to synthesize at a lower cost. Nano-minerals are of the size from 1–100 nm and due to such small size, there is an enormous increase in surface area and thus their biological responses. The biological response studies have signified better retention of nano-minerals as compared to inorganic salts, and consequently leached less to the environment preventing possible pollution. Apart from these, nano-minerals have been shown to enhance growth, egg production and quality, immune-modulation and antioxidant status, and at the same time economize the production by reducing the supplemental dose of minerals and improving the feed conversion ratio. Some nano-minerals and other nanoparticles have strong antimicrobial effects, which have been shown to reduce pathogenic microorganisms in the gut. Nano-minerals seem to be less toxic than conventional mineral sources. Though less, few studies have indicated toxic effects of nano-mineral supplementation at higher dose of application, which should be validated by more programmed studies. Nanotechnology in poultry production system is still in its budding stage and more detailed studies are warranted to validate, establish and search for new effects of nano-minerals as they sometimes produce effects beyond expectation. This review highlights the biological responses of nanominerals on poultry production performance, quality of meat and eggs, tissue retention, immunity, antioxidant activity and antimicrobial actions compared with their conventional mineral sources.

Full text
Abstract:
Amalgamation technologies allowed refiners throughout colonial Latin America to profitably extract silver from a wider variety of metals, including even the most refractory ores. These expanded processing capabilities meant that mineral classification and sorting became even more important, as metallurgists had to identify which silver metals to treat with traditional methods and which ones to refine by amalgamation. The vocabularies used to classify metals provide critical evidence of Indigenous contributions to silver refining in the seventeenth century. By tracing the incorporation and removal of Andean color and spatial vocabularies, this chapter shows how scientific writers and translators replaced Indigenous classifications of matter with a racialized language of metallic “castas” that included “pacos,” “mulatos,” and “negrillos.” The chapter concludes by suggesting how a reading of color signatures in khipus might shed light on Andean miners’ experiences in ways that traditional historiographic methods have not yet allowed.

Full text
Abstract:
Mollusks have a well-deserved reputation for being expert mineralizers based only on their much-admired shell-making abilities. Table 6.1 shows that the reputation is deserved 10-fold as shell formation is just one of many different processes that these animals perform in which biogenic minerals are utilized. The table lists no less than 21 different minerals and about 17 different functions! The list contains both amorphous minerals (amorphous fluorite, calcium carbonate, calcium phosphate, calcium pyrophosphate, and silica) and many crystalline ones, including rather uncommon ones such as weddelite, calcium fluorite, barite, magnetite, lepidocrocite, and goethite. Weddelite, for example, is a calcium oxalate mineral frequently formed pathologically in vertebrates. Certain gastropods use the rather soft weddelite nonpathologically to cap pestlelike objects (gizzard plates) in their stomachs (Lowenstam 1968), which they use for crushing shelled prey. One mollusk, the chambered Nautilus, forms no less than five different minerals. An individual tooth of a chiton contains three different mature minerals that are products of two other transient minerals. In addition to the more familiar functions of mineralized tissues, mollusks use biogenic minerals as buoyancy devices, trap doors, egg shells, and love darts. The varieties of crystal shapes, sizes, organizational arrays, and tissue sites present a picture of overwhelming diversity all within one phylum. It is illustrative to compare the mollusks with the echinoderms. The echinoderms also use minerals for a wide variety of functions, but in contrast to the mollusks they use essentially the same “building material” for many different purposes. Thus, understanding how one echinoderm mineralized tissue forms provides insight into how most of the others form. This is not so with mollusks. It seems futile to expect that they too have adapted one basic process to form all their mineralized tissues. It seems just as futile to look for a different explanation for each type of mineralized product. The mollusks force us to seek a level of understanding of mineralization that identifies common approaches, strategies, and principles and, at the same time, appears to dispel any “dreams” about discovering the mechanism of mineralization. The mollusk phylum contains seven different taxonomic classes.

To this point we have assumed the existence of a basis of chemical components that corresponds to the system to be modeled. The basis, as discussed in the previous chapter, includes water, each mineral in the equilibrium system, each gas at known fugacity, and certain aqueous species. The basis serves two purposes: each chemical reaction considered in the model is written in terms of the members of the basis set, and the system’s bulk composition is expressed in terms of the components in the basis. Since we could not possibly store each possible variation on the basis, it is important for us to be able at any point in the calculation to adapt the basis to match the current system. It may be necessary to change the basis (make a basis swap, in modeling vernacular) for several reasons. This chapter describes how basis swaps can be accomplished in a computer model, and Chapter 9 shows how this technique can be applied to automatically balance chemical reactions and calculate equilibrium constants. The modeler first encounters basis swapping in setting up a model, when it may be necessary to swap the basis to constrain the calculation. The thermodynamic dataset contains reactions written in terms of a preset basis that includes water and certain aqueous species (Na+, Ca++, K+, Cl-, HCO-3, SO4- -, H+, and so on) normally encountered in a chemical analysis. Some of the members of the original basis are likely to be appropriate for a calculation. When a mineral appears at equilibrium or a gas at known fugacity appears as a constraint, however, the modeler needs to swap the mineral or gas in question into the basis in place of one of these species. Over the course of a reaction model, a mineral may dissolve away completely or become supersaturated and precipitate. In either case, the modeling software must alter the basis to match the new mineral assemblage before continuing the calculation. Finally, the basis sometimes must be changed in response to numerical considerations (e.g., Coudrain-Ribstein and Jamet, 1989). Depending on the numerical technique employed, the model may have trouble converging to a solution for the governing equations when one of the basis species occurs at small concentration.

Abstract:
This book examines the resilience shown by the American Middle West—Iowa, Kansas, Nebraska, Minnesota, Missouri, North and South Dakota, Arkansas, and Oklahoma—despite going through profound social upheavals during the half century that began in the 1950s. It shows that the Middle West has undergone a strong, positive transformation since the 1950s—a time when many families were still recovering from the Great Depression. The transformation is surprising because it took place in the nation's heartland. The region's economy fared surprisingly well; agribusiness was flourishing; elementary and secondary education was among the best in the nation; the region was known for innovative medical research and biotechnology. The chapter suggests that one precondition for the social change that has happened in the Middle West is the fact that the region largely comprised rich land with vast potential for crops and livestock as well as mineral wealth.

Abstract:
Correspondence analysis, a non-parametric principal component analysis, has been used to analyze heavy mineral data so that variations between both samples and minerals can be studied simultaneously. Four data sets were selected to demonstrate the method. The first example, modern sediments from the River Nile, illustrates how correspondence analysis brings out extra details in heavy mineral associations. The other examples come from the Plio-Quaternary "Bourbonnais Formation" of the French Massif Central. The first data set demonstrates how the principal factor plane (with axes 1 and 2) highlights relationships between geographical position and the predominant heavy mineral association (metamorphic minerals and zircon), suggesting the paleogeographic source. In the second set, the factor plane of axes 1 and 3 indicates a subdivision of the metamorphic mineral assemblage, suggesting two sources of metamorphic minerals. Finally, outcrop samples were projected onto the factor plane and reveal ancient drainage systems important for the accumulation of the Bourbonnais sands. Statistical methods used in interpreting heavy minerals in sediments range from simple and classical methods, such as calculation of means and standard deviations, to the calculation of correspondences and variances. Use of multivariate methods is increasingly frequent (Maurer, 1983; Stattegger, 1986; 1987; Delaune et al., 1989; Mezzadri and Saccani, 1989) since the first studies of Imbrie and vanAndel (1964). Ordination techniques such as principal component analysis (Harman, 1961) synthesize large amounts of data and extract the most important relationships. We have chosen a non-parametric form of principal component analysis called correspondence analysis. This technique has been used in sedimentology by Chenet and Teil (1979) to investigate deep-sea samples, by Cojan and Teil (1982) and Mercier et al. (1987) to define paleoenvironments, and by Cojan and Beaudoin (1986) to show paleoecological control of deposition in French sedimentary basins. Correspondence analysis has been used successfully to interpret heavy mineral data (Tourenq et al, 1978a, 1978b; Bolin et al, 1982; Tourenq, 1986, 1989; Faulp et al, 1988; Ambroise et al, 1987). We provide examples of different situations where the method can be applied. We will not present the mathematical and statistical procedures involved in correspondence analysis, but refer readers to Benzécri et al.

Abstract:
Heavy minerals (HMs) are minerals with a specific gravity greater than 2.9 g/cm3. They are commonly highly resistant to physical and chemical weathering, and therefore persist in sediments as lasting indicators of the (former) presence of the rocks they formed in. The presence/absence of certain HMs, their associations with other HMs, their concentration levels, and the geochemical patterns they form in maps or 3D models can be indicative of geological processes that contributed to their formation. Furthermore trace element and isotopic analyses of HMs have been used to vector to mineralisatio
