2.2. Chalcopyrite Ore Processing. The first step in the chalcopyrite processing is to liberate the copper minerals and remove waste constituents such as alumina, limestone, pyrite and silica so that the copper and non-ferrous mineral values are concentrated into a product containing between 20 to 30 percent copper.Web

Copper ore is typically mined through two primary methods: open-pit mining or underground mining. In open-pit mining, large pits are dug into the earth using heavy machinery, and the ore is extracted from the rock. Underground mining, on the other hand, involves tunneling into the earth to reach the copper deposits. 2.Web
