Copper Mining and Production Processes Explained
Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.Metallurgical Testing & Process Design Mineral Technologies,Detailed analysis of results from metallurgical testing inform the development of innovative and cost effective flowsheets for specific ore bodies.
