Analysis of pure copper A comparison of analytical methods.
Copper mostly occurs as sulfide ores, which are heated in air to convert them to copperII oxide.
magnetic separator can recover useful magnetic minerals contained in copper ore.
While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores.
