    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.Concentrating Resolution Copper,The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells. When mixed with water, reagents, and air, the copper minerals produce a bubbly froth. The bubbles with copper are skimmed and filtered to produce copper concentrate.
