Die Berliner Bergakademie und die mit ihr verbundene Sammlung des preußischen Berg- und Hütten-Departements, das Königliche Mineralienkabinett, sind die unmittelbaren institutionellen Vorläufer der geowissenschaftlichen Institute und Sammlungen, die sich heute im Museum für Naturkunde der Humboldt-Universität befinden. In der Zeit ihres Bestehens erlebten diese Einrichtungen eine beachtliche Entwicklung. Am Königlichen Mineralienkabinett waren als Leiter und Lehrer der Mineralogie und Bergbaukunde nacheinander drei Bergbeamten tätig, Carl Abraham Gerhard als ihr Gründer, danach für kurze Zeit

Abstract:

Actual improvements in rod or wire production e.g. in relation to power requirements, energy consumption and final material properties demand powerful simulation tools for process optimization, pre-setting calculations or automation. The groove pass design model of TU Bergakademie Freiberg was developed and applied for this purposes. This paper gives a short review of the history of this model approaches and highlights some important stages of development.

The German-Brazilian geoscientific relations may be classified as follows: Brazilians sent to visit and to study in German institutions, especially in the Bergakademie Frieberg; German functionaries invited by the Portuguese government to work in mining activities in Brazil; German trave

Low pressure casting is a very well established process for the casting of aluminium alloys. In the field of ferrous materials, however, the process has so far only found a few applications.

Copper is one of the most common tramp elements in steel scrap. It originates from recycling of copper-alloyed steels, such as weather-resistant construction steel (up to 0.3 mass% Cu) or austenitic stainless steels (up to 3 mass% Cu). In both cases, corrosion resistance is increased. Certainsteels, on the other hand, be alloyed with Cu to influence the Ms point, ductility and/or antiseptic properties. However, copper increases the risk of hot shortness and cold work hardening in low-alloyed steels, which is even more pronounced if Sn is also present in the alloy. Furthermore, Cu is frequently

Abstract The production of castings by green sand moulds is a very important method for the manufacture of final products for different sectors of industry. In this green sand moulding process the quality of castings depends strongly on the quality of the mould, which in turn is determined by parameters such as the type of foundry machine, the characteristics of the moulding sand and the specifications of the patterns. The mould’s stability for use casting is achieved by filling and compacting moulding sand. This means, that the clay-bonded moulding sand is changed from the free flowing to the

The efficiency of phytoextraction depends on numerous soil-associated and plant-associated factors (e.g. concentrations of target elements in potentially plant available soil fractions, rhizosphere processes and uptake mechanisms of plants). The aim of this study was to evaluate the effect of different soil properties (pH, compost amendment) on the mobility of selected target elements for phytoremediation (As, Pb, Cd, Zn) and phytomining (Ge, REEs) in soil and shoot concentrations in Phalaris arundinacea. Until today, only little is known about the influence of soil-associated factors on the availability of trace elements for Phalaris arundinacea, especially for the target elements Ge and REEs. In a field experiment we cultivated 10 different genotypes of Phalaris arundinacea on four different substrates with similar element concentrations but different pH-values (pH 6.6 – 7.8) and levels of compost amendment (5l /m2 compost or without compost). On each of the substrates we cultivated Phalaris arundinacea (genotypes) with two replicates on plots 4 m2 each and installed suction cups to collect soil solution. After harvest concentrations of Ge, REEs, P, Fe, Mn, Zn, Pb, As and Cd in shoots and soil solution were determined with ICP-MS. Compared to the slight alkaline soil, acidic soil conditions significantly increased shoot concentrations of Fe, Mn, As, Cd, Pb and REEs. Under acidic soil conditions addition of compost further increased the concentrations of all investigated target elements in shoots of P. arundinacea except of As. In soil solution only concentrations of Fe and Mn significantly increased due to the compost amendment, while concentrations of P, Ge, REEs, Cd and Pb decreased. Lower concentrations of elements in soil solution may result from increased adsorption of the elements onto soil particles (in case of P and Ge) or the uptake of the elements by plants (in case of Cd and Pb). We conclude that amendment of soil with compost seems to be a sustainable approach to enhance the uptake of plant nutrients such as Fe and Mn as well as REEs into shoots of Phalaris arundinacea and to reduce the mobility of potential toxic trace elements (Cd, Pb) in soil solution.

Abstract:

AbstractThe hydrodynamics of a Top Submerged Lance (TSL) slag bath are investigated here by means of Computational Fluid Dynamics (CFD) simulation. The object of the study is the pilot-scale furnace located at TU Bergakademie Freiberg, where air is injected beneath the slag bath with a top lance. The fluid dynamics system is evaluated at operating conditions, with experimentally measured slag physical properties and real flow rates. The numerical approach is based on the Volume Of Fluid (VOF) model, a front-tracking method that allows the interface to be geometrically reconstructed. Using a fi
