Copper Mining and Processing: Everything you Need to Know

The Basics of Copper Mining and ProcessingWhat Is Copper Used for?The Copper Mining ProcessMined 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. The oxides are smelted to produce matte, which then undergoes several refining processes.

Open-Pit Mining Methods

AdvantagesIssuesTypesUsageCostTechnologyOperationConstructionServiceEarly historySimple forms of open-pit ore mining include excavation and loading of overburden and ore by hand into wagons or trucks and excavation and removal of overburden and ore by means of animal-drawn slip or drag scrapers.
