purification of copper by electrolysis metal extraction ...

Copper ores are concentrated by a technique known as froth flotation. The ores are roasted to drive off unwanted water and convert them to a more suitable chemical form for reduction to copper metal. After reduction of the ore the liquid copper can be run off from the coke fired copper smelter (furnace).

How Mining Companies are Reducing the Environmental Impact ...

Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left. We can't go on this way, and politicians agree. It's why mining companies are working to reduce the environmental impact of mining through green mining processes.
