    4. Beneficiation of Copper Ore. Top: Slurry tanks for sulfide ore. Bottom: Leach field for removing copper from oxide ore. Sulfide ores are mixed with water and special chemicals creating a slurry. The slurry, when agitated causes the copper sulfide minerals to float at which point they are skimmed off the surface and eventually dried.

  • Properties of Copper Ores

    Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.

  • Flotation of Copper oxide ore

    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 ...

The gangue comprised pyrite, carbonate, calcite, and ...

  • Copper Mining and Extraction Sulfide Ores

    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: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.

  • Copper Oxide Ore

    Copper Oxide Ore Copper also occurs to a lesser extent in oxidized minerals (carbonates, oxides, hydroxy-silicates, sulfates). Copper metal is usually produced from these minerals by leaching, solvent extraction, and electrowinning. These processes are also used to treat chalcocite (Cu2S). The other 20% is obtained through hydro-metallurgy. ...

  • 12.3 Primary Copper Smelting

    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.

  • How to covert copper II oxide to copper

    Copper Oxide (II) = CuO which is black in colour. Copper = Cu which is brown in colour. Now, CuO + H2 (Hydrogen Gas) → Cu + H2O (Water) This is an example of a redox reaction, where if Hydrogen Gas is passed over CuO, then it changes into Cu, the ...

  • Electrowinning Copper Chemistry Tutorial

    Copper ores are usually copper oxides, copper sulfides or copper carbonates. Most copper oxide ores do not contain a high enough percentage of copper to make direct smelting of the ore economically viable. Electrowinning can be used to extract the copper from these copper oxide ores.

  • COPPER Copper production

    Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
