Concentrate

In mining, concentrate is partially purified ore. It is produced by mixing ground ore with water and blowing air bubbles through the water. These carry mineral particles to the surface. This is the final purely mechanical step in the process, and is the output of mining as such. As such, concentrate production is a measure of the output of a mine (or mines). The concentrate is then smelted to

Copper Concentrate Processing Equipment

 · However, the main copper processing equipment for copper ore is same as other mining processing steps, including crushing, grinding, flotation separating and dewatering. Given the sliming and associated ore phenomenon of copper ore, additional copper concentrate process and multiple mining machines are necessary. Therefore when deciding the copper ore concentration equipment, the analysis of
