3 Processing Of Copper Ore

  • Heap Leaching

    Heap Leaching

     · Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods. Thirtyseven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,000 ounces ...

    The ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% copper.

    Copper Ore is a resource that can be gathered from copper ore veins. Copper ore is only found within Granite.. It is most abundant in the Tundra or Ice biomes, especially 2030 blocks below the surface.. Copper Ore is clearly distinguishable from the surrounding rock due to its reddish, mottled appearance.

     · When a crashed ore containing nickel, copper and cobalt is treated with aqueous ammonia . under suitable pressure, ammonia selectively leaches these metals by forming their soluble complexes viz. [Ni(NH 3) 6] 2+, [Cu(NH 3) 4] 2+, and [Co(NH 3) 5 H 2 O] 3+ respectively from the ore leaving behind the gangue, iron(III) oxides/hydroxides and aluminosilie.

    3. Processing of Copper Ore. The process varies slightly depending on the type of ore that is being mined. Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 2 inches.
