flotation oxidised copper ore
BULK FLOTATION OF COMPLEX COPPER ORE
In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore. Selectivity between chalcopyrite and sphalerite, in principle, is determined by the type of copper minerals present in the ore.

The volume capacity of the mixed ore flotation plant increased from 900 m 3 to 1500 m or 2100 m3, depending on whether the 300 m3 cells are used for mixed ore flotation or not. In late 2011, an extension of the CPS plant was commissioned, to increase the number of sulphidisation intervals to the current four stages.
Copper Ore Oxidised
Oxidised copper ore vs Copper oxide ore Oxidised copper ore bodies are copper ore bodies which are oxidised in a geological sense. Not a chemical sense. ie; they are products of oxidation of reduced copper minerals (sulphides) to "oxide" minerals such as carbonates, within the regolith.
The effects of electrical comminution on the mineral ...
• The iron preferentially oxidised on the chalcopyrite surface of the HVP product. • Copper sulphate was formed from further oxidation of the copper sulphides. • An attrition grinding removed the oxidised layer from the surface of the particles. • HVP treatment improved the overall flotation recovery and the concentrate grades.
copper extraction and purification
Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining.

Role of sodium sulfide in the flotation of oxidized copper ...
This paper reviews uses of sodium sulfide in the flotation of oxide minerals of copper, lead, and zinc. The activation and depression effects of sodium sulfide are of particular importance because of their applications with oxidized lead and copper ores.
Effect of pulp potential on the flotation of a sulfide ...
Surface oxidation of secondary minerals, such as chalcocite, bornite and digenite, present in the Salobo copper ore makes their flotation difficult and requires excessive reagent consumptions. Two possibilities for reducing the collector and fr other additions were investigated.
Copper production environmental impact
• Rocks are crushed in a series of crushers. Sulfide ores are further reduced through a 'wet grinding' process that ensures a particle size suitable for the flotation process. Copper leaching. Sulfide ores and froth flotation. Sulfide ores are mixed with water and a surfacant creating a slurry.
