Historic Copper deposit with intercepts up to 28.4 CU. The Mt Oxide project is a historic copper deposit that has yielded multiple high-grade economic copper intercepts. This dates back to 1914-15 when historical mining operations at Big One Deposit are reported to have produced 9.4t Cu.

Jul 12 2021 Copper ore beneficiation methods. Before the beneficiation of copper ores crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment and the final particle size of the copper ore is reduced to 0.15-0.2mm.

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example FeOs SiO 2 s→ FeO.SiO 2 slag This is very similar to the removal of impurities in the blast furnace.

The floatability of copper oxide ores is generally worse than that of copper sulfide ores and is greatly influenced by the existing form of copper in minerals and gangue composition. For example when copper is in the form of carbonate malachite blue copper ore the flotability is relatively good while the flotability of silicate silica.

charge material of copper concentrate mixed with a siliceous flux often a low-grade copper ore is heated in air to about 650 C 1200 F eliminating 20 to 50 percent of the sulfur as sulfur dioxide SO2. Portions of impurities such as antimony arsenic and lead are driven off and some iron is converted to iron oxide.
