Copper Mining Knowledge
The main ores of copper are: chalcopyrite, bornite, malachite. About 200 years ago the UK was an important world source of copper and there were mines in Cornwall and Wales. These mines have now closed and today the biggest copper mines are in Chile and North America. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1000 kg of ore. The ores are extracted by either traditional mining (open pit or underground) or by leaching. The copper is then recovered using physical and chemical techniques.
Portable Crusher for Copper Mining
The Portable Crusher is a common copper crusher, Gulin® is a professional copper mining portable crusher manufacturer in China, and our portable crushers have four series: portable jaw crusher, portable cone crusher, portable impact crusher and Track mounted crushing plant. They are widely used in copper, coal, gold mining and processing process.
Copper mining portable crusher include: primary jaw crusher or secondary cone crusher or tertiary impact crusher can be used in conjunction with screens to provide a highly efficient production line for the operator.
Copper mining process
There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached.
First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers.
Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper. The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper.
Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX). The SX process concentrates and purifies the copper leach solution so the copper can be recovered at a high electrical current efficiency by the electrowinning cells.
