The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 05%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.

use of lime copper flotation

Improving copper flotation recovery from a refractory Lime is commonly used as a pH regulator and depressant against iron minerals during the flotation recovery of copper minerals from copper porphyry sulfide ore It can also depress copper oxide, secondary copper sulfide or gold minerals ( Allan and Woodcock, 2001 , Sun, 2001 , Liu et al.

Copper processing

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed or Native copper is simply the metal found unadulterated in nature Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselv.

Processing copper-porphyritic ore

If molybdenite flotation is required to separate it from copper sulfides, the pH should be no more than 11 to provide pyrite depression, and lime is added with a small amount of cyanide and soluble silica is used to suppress gangue minerals within the molybdenum flotation circuit The molybdenum recovery from bulk copper-molybdenum concentrate.

Copper Sulfide Ore Flotation Technologies

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as “collect early, loss early” and “more crushing and less grinding”.

Copper Ore Processing Plant,Equipment For Sale

Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.

The Recovery of Copper from Smelting Slag by Flotation

Abstract Aiming at the recovery of copper from smelting slag, a flotation approach was studied It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

Copper Mining and Extraction: Sulfide Ores

Stage 2: Froth flotation , Formation of blister copper by reduction of copper sulfide: Cu 2 S(l) + O 2 (g) → 2Cu(l) + SO 2 air blister copper gas Stage 6: Anode casting The blister copper produced by this process is 99% pure copper The name ‘blister’ copper comes from the fact that this final process produces bubbles of sulfur dioxide.
