Copper Mining & Extraction Process Flow Chart

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).the copper mining process from underground and open pits,Mining can take place through open cut or underground mining methods. At Griffin Coal's Collie mines open cut mining methods are used. The mining process involves the removal of overburden and extraction of coalCopper Mining and Processing: Everything you Need to Know,Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.
