Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger .

This dust is then mixed with water and reagents in our zinc-lead concentrator's flotation circuit. The reagents help us to separate the valuable mineral content from waste rock. Air is forced through the slurry creating bubbles, which float to the surface and attract and bind to the zinc or lead particles.
Copper Mining and Processing: Everything you Need to Know
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.
