the process in mining copper - Grinding Mill China. Copper ore a valuable mineral source for all countries. Copper ore is an ore which can produce copper metal by crushing in ore crushing plant, grinding in Ball mill and smelting in a furnace along with a piece of tin ore.

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore body. ...

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.

The copper minerals are then ground up even finer and purified by another flotation process. The dried copper concentrate of about 28 percent copper is shipped to the smelter. It represents less than one percent of the material removed from the mine.

TENORM: Copper Mining and Production Wastes . Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. ... Converting: Finally, matte copper is converted into a copper-rich slag, which is then returned to the leaching process and separated from ...

The next stage, smelting, is a process of heating and melting the copper concentrates to cause a chemical reaction, which removes the copper from other elements in the ore. At the smelter, we produce large 750-pound anodes and transport them by rail to the Refinery.

The process from exploration site selection, through target generation, resource evaluation and ore deposit definition costs tens of millions of dollars, before the potential for a copper mine is confirmed, with that the path to production is still many years away.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
