One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper ( II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper ( II) carbonate to produce a blue solution of copper ( II) sulfate. Scrap iron is then added to this solution, and pure copper.

2. Grinding process. The copper ore processed into granules is screened by a vibrating sieve and sent to a ball mill for grinding and crushing. Here also need to use an auxiliary equipment – classifier. It …

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.
