Copper Production Grinding

Copper Ore Processing Methods

Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced,...

Copper Mining and Production Processes Explained

The copper is purified to 99.99% by electrolysis. The production route described above shows the progression from a rock containing about 0.2% copper to a copper cathode of 99.99% purity. Leaching. Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid.

Copper Mining and Processing: Processing of Copper Ores ...

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.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Copper Mining & Extraction Process Flow Chart

Copper Mining & Extraction Process Flow Chart. This is the same process for both copper and molybdenum porphyries. The smelter is basically a large furnace which melts the concentrate and drives off the sulfide to leave molten copper metal this is still contains impurities and it needs to be refined further to make it a salable product.

2. Mining Methods - Copper

Open pit mining is a technique used to extract copper ore near the earths surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earths surface. Underground mining is used when the copper ore is not near the earths surface.
