Abstract:

Buffaloes have great potential to be developed as one of the main dairy animals in Sri Lanka because of their higher adaptability to local conditions compared to European dairy cattle breeds. Processing dairy products such as curd, cheese, and yoghurt from buffalo milk has several advantages due to its greater quantities of total solids, solid-nonfat, and protein. However, milk composition and coagulation properties largely depend on the breed. Therefore, this research aimed to investigate the milk composition of three major buffalo breeds in Sri Lanka.

Abstract Although discussions of Nigeria’s extractive industry have traditionally revolved around oil and gas, the importance of solid minerals cannot be under-estimated. Despite their minor contribution to Nigeria’s gdp, they offer an alternative route to economic diversification and a sustainable economic path. However, as is the case of the oil economy in Nigeria, the solid minerals sector is plagued by “resource curse” indices as a result of misgovernance.

Abstract:

Examining the kinetics of solids’ thermal decomposition with multiple overlapping steps is of growing interest in many fields, including materials science and engineering. Despite the difficulty of describing the kinetics for complex reaction processes constrained by physico-geometrical features, the kinetic deconvolution analysis (KDA) based on a cumulative kinetic equation is one practical method of obtaining the fundamental information needed to interpret detailed kinetic features. This article reports the application of KDA to thermal decomposition of clay minerals and indigo–clay mineral

Government at different times had implemented policies and programs to trigger the performance of the solid mineral sub-sector in Nigeria positively yet it contribution to the GDP remains dismal. Hence, the study focused on the impact of trade openness on the growth of solid mineral Sub-sector in Nigeria from 1981 to 2020. The study employed Auto Regressive Distributed Lag (ARDL) as the modeling technique. Solid mineral subsector (SLM) was used as the dependent variable while Trade openness (TPN), Foreign direct investment (FDI), Foreign portfolio investment (PFI), Remittances (RMT) constitute

Abstract:

Compositional and textural variations in the rinkite group, seidozerite supergroup minerals, batievaite-(Y), hainite-(Y) and close to them titanosilicates from the Sakharjok massif were studied. Statistical analysis allowed for defining two major substitution schemes leading to batievaite-(Y) and cation-deficient titanosilicates forming: Ca2+ + Na+ + F− ↔ □ + Y3+ + (OH)− and Ca2+ + Na+ ↔ □ + REE3+. Batievaite-(Y) and other cation-deficient titanosilicates are the earlier minerals formed by solid state transformation of the primary full-cation phase. Hainite-(Y) is a later mineral. It forms rim

Mineralogical-analytical methods and methodologies for predictive assessment of solid minerals essentially determine the feasibility and tactics of developing raw materials, and, if necessary, the possibility of replacing, first of all, strategic raw materials with others. Using the example of strategic types of minerals: manganese ores of the Usinsk and bauxite deposits of the Upper Shchugor deposit, the possibilities of mineralogical study of ores with complex composition and structure as part of assessing their quality are considered.

The ICDD has developed a microanalysis tool to help scientists identify minerals from their elemental analyses, most typically micro-XRF or a microprobe analysis. Many minerals have characteristic elemental profiles that can often distinguish the mineral from others by their composition differences.

In this study, oxidizing roasting, segregation roasting, and magnetic separation are used to extract cobalt and iron from refractory Co-bearing sulfur concentrate. The Co-bearing sulfur concentrate containing 0.68% Co, 33.26% Fe, and 36.58% S was obtained from V-Ti magnetite in the Panxi area of China by flotation. Cobalt pyrite and linneite were the Co-bearing minerals, and the gangue minerals were mica, chlorite, feldspar, and calcite in Co-bearing sulfur concentrate. The results show that cobalt is transformed from Co-pyrite and linneite to a Co2FeO4-dominated new cobalt mineral phase, and

Beryllium is a chemical element composition of the Group 2 of the Periodic Table of Chemical Elements. It does not crystallize as a natural solid and exhibits a crustal abundance of 2.8 ppm. It is a chemical element among the trace elements with low representativity, together with erbinm and bromine. It shows a big chemical reactivity, and a low abundance in the chemical composition of minerals (only 96 minerals have beryllium in their chemical compositions). The principal beryllium-bearing minerals for industrial usages are beryl and bertrandite, and secondary sources are helvite, chrysoberyl

Purpose. In archaeological sites of the Early Iron Age and the Hunno-Sarmatian period, there are very similar bead sets, among which carnelian products stand out. Carnelian has a high hardness coefficient and its drilling, even with modern tools, it is extremely technological and time-consuming. The important detail of the drilling process is the configuration of the cutting part of the tool, which leaves specific traces on the stone. In order to reconstruct this main operation, we conducted a series of experimental traceological studies, including the study of traces on the walls of the chann

Abstract:

The Zero Liquid Discharge (ZLD) process involves several stages, including pretreatment, evaporation, crystallization, and solid waste management. Pretreatment removes solids, oils, and contaminants from the wastewater. Evaporation applies heat to evaporate water, leaving behind concentrated brine or salts. Crystallization or membrane filtration further separates dissolved salts and minerals, ensuring the treated water meets required quality standards. Solid waste generated during the process is appropriately managed or repurposed.

Against the background of huge mineral reserves concentrated in the Arctic zone, it is important not to overlook the deposits hidden beneath the water surface, because the true resource potential of the Far North extends to the Arctic shelf. In this regard, the task of studying the complex relationship between the properties of seawater and the extraction of solid minerals from the bottom of the Arctic shelf becomes relevant.
