The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance.
This free report reveals six junior mining stocks that are soaring on the back of ...
This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinc-cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.
