Extraction of Copper from Copper pyrite | Grade 12 Science ...

Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore over quite a long time and on a huge scale with a acid such as sulphuric acid to produce a very dilute copper II sulphate solution. Concentration of the copper II sulphate solution by solvent extraction

  • Nickel processing - Extraction and refining | Britannica

    In cases such as the Sudbury deposit, where the copper content of the ore is almost equal to that of nickel, the concentrate is subjected to a second selective flotation whereby the copper is floated to produce a low-nickel copper concentrate and a separate nickel concentrate, each to be processed in its respective smelting line

    In flotation process, finely ground mixed with water and special reagents, is agitated by mechanical and pneumatic devices. These produce air bubbles in ore-water mixture, or slurry. reagents provide an attraction between surface of minerals and air bubbles

Smelting • 80% is produced this way • Heat strongly in a furnace with air + Oxygen + Sulphur Sulphide Dioxide • Then use electrolysis to purify the • Expensive as needs lots of heat and electricity 2. Sulphate • Add sulphuric acid

  • Extracting iron and copper - Reactions of metals - AQA

    Copper mostly occurs as sulfide ores, which are heated in air to convert them to copper II oxide. Molten copper can be produced from copper oxide by heating with carbon: Copper oxide + carbon →

  • Mining

    Mining is the of valuable minerals or other geological materials from the Earth, usually from an body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay

  • Copper extraction

    Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated concentrated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals such as chalcopyrite, th
