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.
The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells. When mixed with water, reagents, and air, the …

The thickener is a very basic piece of machinery that performs its job in an easily understood manner. It simply provides a holding area large enough to allow the concentrate time to settle to the bottom. Once there, there are RAKES that rotate pulling all of the mineral to the center of the thickener. Prom that point it is pumped to the filter.
