germanium recovery method from slag processing of complex ore

As an example, starting with a zinc ore whose average germanium content is of the order of 30 grams per metric ton, i.e. 0.003%, it is found that the germanium concentration in zinc removed from the end of the reboiling columns varies between approximately 0.6 and 0.8%. Nov 26, 2008 The ore body (29 08 34 N, 103 39 57 W) occurs in a carbonate solution collapse breccia, the known extent of which reaches approximately 100 m below the surface (Figs. 1 and 2).Two major ore types exist one consisting primarily of zinc and lead sulfides and a sulfide-poor type (oxidized ore) of Zn silicates, carbonates plus oxide minerals.

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). The element is commercially obtained from the dusts of smelters processing zinc ores, as well as recovered from combustion by-products of certain coals. A large reserve of the elements for future uses in insured in coal sources. Germanium can be separated from other metals by fractional distillation of its volatile tetrachloride.
