Abstract
1. Process for obtaining an upgradable germanium concentrate from sulphur-containing metal concentrates in which the sulphur-containing concentrate is treated with a quantity of soda such that the sulphur content is fixed as sulfate, and is subsequently roasted under oxidizing conditions, the product of roasting leached with sulfuric acid, and germanium precipitated from the solution.
