Flotation of upper zone copper sulfide ores Exxon

It is well known that the rate of flotation and overall recovery of copper sulfides, such as those in porphyry ores, are substantially lower with ores which come from upper zones of ore bodies. This decrease in copper recovery and flotation rate is believed due to the weathering effects near the ground surface which results in partial oxidation

Flotation and Tailing Discarding of Copper Cobalt Sulfide

The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical characteristic, the liberation degree of useful

Copper ores Danafloat

Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

How to Process Copper Ore: Beneficiation Methods and

2021-10-28  Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
