electrolysis of copper oxide ore Solution for ore mining
Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is copper is formed if copper oxide is Copper Chemistry. The Extraction of Copper Copper is extracted from its ore by two the purity of the plated copper product in the electrolysis Copper(I) oxide occurs native as the red HowStuffWorks “Copper Info”

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis.

The Extraction of Copper - Chemistry LibreTexts
2021-6-7 Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the

Extracting antimony from high arsenic and gold
2019-6-1 This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.
