concentration of copper in different ores

  • Copper extraction Wikipedia

    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 Copper AgeThe Bronze AgeThe Middle Ages and LaterMiningAlso in This IssuePre-dynastic Egyptians knew copper very well. In hieroglyphic writing the symbol used to denote eternal life, the ankh, was also used to represent copper. The Greek philosophers later adopted the symbol, slightly modified, as . The connection between eternal durability and the lifetime cost-effectiveness of copper and its alloys is surely not coincidental!The Egyptians obtained most of their copper from the Red Sea Hills, but copper predates ancient Egypt by several millennia, and it is now k.

  • Extraction Of Copper Mining, Concentration, Smelting

    The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

  • Concentration of Ores: Hydraulic Washing, Froth Flotation

    Hydraulic WashingMagnetic SeparationFroth Flotation ProcessLeachingBayer ProcessThis method is based on the differences in weight between the gangue and the metal. Generally, the metal particles of the ore are heavier than the impurities. So we use the principle of gravity separation to separate the two. Here crushed ore is mixed with an upward stream of running water. The lighter particles of the gangue wash away in the running water. The heavier metal particles settle down and can be separated easily. We use this method for ores that contain lead and tin since these are relatively heavier.
