A Review of the Cyanidation Treatment of Copper-Gold …
high percentage of oxide copper causes problems in the concentration process, decreasing the copper content. In order to increase the e ciency of the concentration process, it is necessary to treat the copper oxide component by leaching the grinded ore prior to the flotation, or by leaching the flotation tailings coming out from the ...

Turning Copper Ore into Copper: What are the Processes?
After the air is brought up through the water, bubbles form that float the water-repellent copper particles to the surface of the water. This separates out the froth which has 30% copper, 27% iron, and 33% sulfur. The flotation process gets rid of impurities in the ore, where there may also be lead and other vital metals in our society …
