Dec 14, 2020 · How copper is produced Mining For Zambia. Oxide ore – treatment process: Copper is liberated from oxide ore through a chemical process known as leaching and solution extraction. The final step is electrowinning, which uses an electrical current to produce sheets of copper that are % pure and ready for shipping to world markets. Step 5.
This crushed ore and frit can be treated with sulfuric acid and thus the process here onwards followed is the same for both the ores. On treatment with H2SO4, the beryllium along with other metals, present in the ore get dissolved, resulting in a water soluble sulfate.
The ore in this egory is typically defined as '3/4" crushed oxide' or '3/4" crushed transition'. Ore Category 3 (1/2" Crushed ore) – low cyanide soluble ratio ores are crushed to a P80 of ½". The crushed ore is mixed with soda ash to induce an alkaline 'preoxidation' process.
