Purchase and Processing of Copper Ores. We purchase high-grade copper ores from small and medium scale producers to be processed in a modern 2,500 tpd concentrator plant to be located outside Casa Grande in Pinal county, Arizona. We offer competitive prices for the copper ores based on the copper market price.

Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

The copper ore beneficiation plant uses three processes: crushing, grinding and beneficiation. It's just that the selection of individual copper ore processing equipment and beneficiation technology will be slightly different. Among them, in the crushing process, the use of three-stage closed-circuit crushing can well complete the work of ore ...

The flotation process, which was responsible for the almost complete change in equipment, has also undergone marked changes since its introduction in large-capacity concentrators. Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants.

As a result each mixer settler is ½ the size of those in the 2×1 circuit and the total settler area is only 66.7% of that of the 2×1 circuit. The cost saving is estimated to be about 29% which gives a capital cost of $5.0 million. The electrowinning capital cost is the same for each plant and is based on a copper production of 27.2 tonnes/day.
