Copper Nickel Flotation

Batch Copper Nickel Flotation Tests. Testing of the shaft sample was conducted with sodium isopropyl xanthate collector throughout the laboratory test series. The change from isobutyl zanthate (which was used with the pit sample) to isopropyl zanthate was for convenience only and had little or no effect on the flotation results.

(PDF) A Review of the Flotation of Copper Minerals

Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.
