  • Recovery of Copper by Solution Mining Techniques AZGS

    Copper as well as a number of other commodities are harvested by solution mining methods. Water soluble salts such as potash (sylvite), rock salt (halite), thenardite (sodium sulfate) and nahcolite (sodium bicarbonate) are commonly derived from massive sedimentary deposits by in situ methods.

  • Copper mining. From ore to copper. SchoolScience.co.uk

    Mining Copper can be extracted from its ore by 1. Traditional mining. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations.

  • Mining

    Mining techniques can be divided into two common excavation types surface mining and sub surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.
