The finely crushed ore is concentrated by FrothFloatation process. The finely crushed ore is suspended in water containing a little amount of pine oil. A blast of air is passed through the suspension. The particles get wetted by the oil and float as a froth which is skimmed. The gangue sinks to the bottom.

Conservation of copper ore To date only about 12% of known copper resources have been mined. However copper ore is a finite resource and it makes sense to conserve ore by recycling. Economics It is cheaper to recycle old copper than to mine and extract new copper. Recycled copper is worth up to 90% of the cost of the original copper.

In fact all the high grade ore was mined and directly shipped to smelters in 1970. The remaining oxide ore and the mixed and low grade sulfide ore was crushed for heap leaching. In the pit, similar low grade ore was blasted from the walls of the pit for leaching in the bottom of the pit.

How to Inlay Copper Into Wood By Marjorie Gilbert. SAVE; The art of inlaying wood with copper dates back to the Qing Dynasty in China (), when elaborate designs were inlayed in wood with copper plate and often enamel. The art of copper inlay is also used .

Silver is extracted from the oreargentite ((Ag_2S)). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide (Na [Ag(CN)_2]).

Within the pyrometallurgical route, the mined ore is crushed and milled, followed by a concentration step using flotation. The obtained copper concentrates contain on average 30 percent copper, but grades can

Separating Minerals by Floatation Copper processing example A high pH is important in the processing of copper ore to maximize this mineral's floatation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity.
