The Basics of Copper Mining and Processing. 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.
ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is delivered to the crusher(s) to be reduced in size. At this stage, much of the moisture with the ore may be
