    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.
