The present invention relates generally to a process for recovering copper and/or other metal values from a metal-bearing ore, concentrate, or other metal-bearing material using pressure leaching and direct electrowinning More particularly, the present invention relates to a substantially acid-autogenous process for recovering copper from chalcopyrite-containing ore using pressure leaching .
Rich copper concentrate is produced from crude copper sulfide ore by means of a flotation process that takes advantage of the physical and chemical properties of small copper ore particl To maximize the yield of copper, pH control is necessary in the flotation tanks Crushed ore (containing 1 to 2 % copper), along with water and a lime .
Agitated Tank Bioleaching Bioleaching processes in mechanically-agitated tanks are usually applied for the treatment of flotation concentrates derived from sulfidic or The valuable components in these concentrates can be gold, uranium and a variety of base metals such as copper, nickel, zinc and cobalt
processes in copper mining hopper tanks - Gold Ore Mining Washing Plant Drum Trommel Screen Washer Gold Ore Mining Washing Plant Drum Trommel Screen Washer Machine , Find Some larger wash plants have grizzlies set up directly over the hopper when the concentrates and gold are flushed from the sluice box into a container/tank
2 Corrosion in storage tanks Corrosion is also a problem during fuel storage in storage tanks Corrosion leads to the formation of products which are likely to cause changes in the quality of fuels (affecting their physical and chemical properties), may accelerate oxidation of hydrocarbon ingredients of the fuel – this leads to higher acid values and to the development of gum and sludge in .
Stage 3: Roasting At this stage of the process, the chemical reactions begin They convert the copper minerals into copper metal We can illustrate the types of process using the example of chalcopyrite – CuFeS 2From the formula, it is clear that iron and sulfur have to be removed in order to produce copper

Electrorefining of Copper 1 Electrorefining – General Introduction In an electrorefining process, the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis, ie the electrode reactions are, at the anode: M → Mn+ + ne-and at the cathode: Mn+ + ne-→ M
The molten copper, which is about 995% pure, is then poured into molds to form large electrical anodes, which act as the positive terminals for the electrorefining process 9 Each copper anode is placed in an individual tank, or cell, made of polymer-concrete
