The copper concentrate processing equipment needed in copper ore processing is complex because of the different property of copper concentrate. However, the main copper processing equipment for copper ore is same as other mining processing steps, including crushing, grinding.
The process plants use conventional flowsheets consisting of crushing, grinding and flotation and the company is a significant producer of both copper and zinc concentrates. Operations are split between two processing plants, namely the Copper Plant and the Zinc Plant. Copper Plant: The installed capacity of the Copper Plant is
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.
process of conversion, in copper or any mineral concentration process is known as beneficiation, because it involves the aggregation of low concentrated valuable minerals between % and 5% into high grade between 15 and 50 % that can be .
