  2. Copper extraction - Wikipedia

    en.wikipedia.org/wiki/Copper_extraction

    Copper(II) ions migrate through the electrolyte to the cathode. At the cathode (reduction reaction), Cu 2+ ions are reduced in copper metal and Cu (s) plates out, but less noble constituents such as arsenic and zinc remain in solution unless a higher voltage is used. [53] The reactions involving metallic copper and Cu 2+ ions at the electrodes ...

    Copper is precipitated as its sulfide as a means to purify nickel leachates. Cementation is the conversion of the metal ion to the metal by a redox reaction. A typical application involves addition of scrap iron to a solution of copper ions. Iron dissolves and copper metal is deposited. Solvent Extraction; Ion exchange; Gas reduction.

  4. Refining (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Refining_(metallurgy)

    The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper (II) sulfate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode. However ...

    Froth flotation cells used to concentrate copper and nickel sulfide minerals. Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. [19]

  6. Extractive metallurgy - Wikipedia

    en.wikipedia.org/wiki/Extractive_metallurgy

    Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...

  7. Non-ferrous extractive metallurgy - Wikipedia

    Copper extraction in particular is of great interest in archeometallurgical studies since it dominated other metals in Mesopotamia from the early Chalcolithic until the mid-to-late sixth century BC. [ 11 ] [ 12 ] There is a lack of consensus among archaeometallurgists on the origin of non-ferrous extractive metallurgy.
