Germanium Statistics And Information

Germanium Statistics And Information

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator.

Germanium Properties, History And Applications

Jun 25, 2019· Germanium is most commonly produced from sphalerite zinc ores but is also known to be extracted from fly ash coal (produced from coal power plants) and some copper ores. Regardless of the source of material, all germanium concentrates are first purified using a chlorination and distillation process that produces germanium tetrachloride (GeCl4).

Metallogenesis Of Germanium—A Review

Metallogenesis Of Germanium—A Review

A few minerals exist with germanium as a main component, such as argyrodite, briartite, germanite, renierite and stottite, but these minerals are extremely rare and do not form rich ore deposits [4,5].As a consequence, germanium is mainly obtained as a by-product of processing zinc ores [4,6–8].On a global scale, only as little as 3% of all ...

Zinc Processing

Zinc Processing

The first stage is the removal of iron as a solid residue in the form of either jarosite (a basic ferric sulfate) or the oxides goethite or hematite. This is then followed by cementation with zinc dust to remove other metallic impurities (including copper, nickel, cadmium, cobalt, and germanium) from the solution.

Germanium ores are rare. The least rare, germanite, is a copper-iron-germanium sulfide with 8% of the element, but even this is not mined. Germanium is widely distributed in ores of other metals, such as zinc, and that which is required for manufacturing purposes is recovered as a by-product from the flue-dusts of zinc smelters.

Heap Leaching Of Gold And Silver Ores

Heap Leaching Of Gold And Silver Ores

Jan 01, 2016· Processing ore in a mill has higher operating costs and requires more capital investment than processing it in a heap. A heap leach typically achieves ∼25% less gold recovery than a mill. The operating cost plus debt service for a medium-sized mill (3000 t/d) is typically $39/t of ore treated, whereas the comparable cost for the heap is $19/t ...
