method of extracting copper rock

Innovations: Introduction to Copper: Mining Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Extraction Of Copper Mining, Concentration, Smelting ...

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

Copper Mining and Extraction Sulfide Ores

Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon.

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.
