The metal is found in
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 theelements for future uses in insured in coal sources.
Germanium can be separated from other metals by fractional distillation of its volatiletetrachloride. The techniques permit the production of germanium of ultra-high purity.
