The richest of them are Germany: argyrodite ag8ges6. Contains 5-7% ge. Isomorphic argyrodite canfilphyte ag8sns6 also contains germanium in an amount up to 1.82% hermanite. Approximate formula of the mineral cu3 (fe, ge) s4. In view of the hesitation of the composition, a number of different empirical formulas are proposed. The mineral contains up to 10% ge, 6-8% fe and an average of 0.5-0.8% ga, found samples with a gallium content of up to 1.85%. A mineral renierite (cu, fe)3(fe, ge, zn, sn) (s, as)4 containing 6.37-7.8% ge was recently found in the Belgian Congo (kapushi region). Germany's minerals are rare, and their large accumulations have not yet been found. They are therefore only a secondary source of receipt for Germany. The bulk of Germany is scattered in silicates, sulphide minerals (mainly spalerite) and sulfosol minerals. In silicates, German isomorphno replaces silicon (ion radii ge4 + = 0.44 a and si4 + = 0.39 a are close). Average content of Germany in various erupted rocks, %: it is evident from these data that germanium in the process of magma differentiation accumulates to some extent in residual melts. The highest concentrations in Germany are associated with pneumotholic processes (especially grazes and associated minerals). Germanium is usually present here as an impurity in spalerite and other sulphides, as well as in sulflustanates. The highest concentration of Germany (0.01-0.1%) is characterized by low-temperature zinc deceptions. The German content of zinc sulphides ranges from 0.0005 to 0.1 per cent, reaching in some cases 0.3 per cent (wurzite). Spectroscopic studies of the spread of Germany in zinc deceptions were performed by f.i. abramov and a.k. rusanov. The results are shown in the table. 87. When zinc concentrates are processed, germanium accumulates in some of the production wastes that produce it. Extensive studies of the spread of Germany in coals, conducted in Russia and abroad, have shown that the content of Germany in different types of coals varies from 0 001 to 0.01%, with Germany concentrated mainly in small metamorphised coals, and anthracite coals contain almost no Germany. It is noted that the content of Germany is higher the lower the ash content of coal: geochemistry Germany is not yet sufficiently studied. Some geochemists (goldschmidt) believe that germanium in coals is primarily associated with carbon rather than mineral constituents. In ashes of stone coals, in some wastes of coke plants, in dust of gas generator plants there is a high content of Germany. Together with zinc waste, they are an important source of production in Germany. It is estimated that out of the 100 million tons of hard coal produced in England in 1 year, 2,000 tons of Germany can be extracted.\n\n\n\n\n\nContact facebookclassmate mirtwitterlivejournalapplications germaniaghydride Germany (germanodorod) sulphides germaniaghalogenides germaniaghernatyoxidiz germaniaproperties germaniaextract thallium from dust from kiln finish extraction thallium and cadmium from dust obtained from melting lead in mine furnaces extraction thallium from zinc waste
