A process for obtaining metal powders BASED ON COPPER AND MINERALS PIRITA COPPER FELLOW

摘要

A process for the beneficiation of ores containing copper, wherein the ore is first brought to the oxide form, because oxides are reduced to metal-powder below the melting point of the metal and that the metal-powder produced, for example, by beneficiation methods, they are freed from impurities, gangue and the like.
