  • Gravity Concentration | Gekko

    Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

  • Mining - Massachusetts Institute of Technology

    In-Situ Leach (ISL) Mining: Some ore bodies, due to ore concentration or the surrounding material, can only be accessed by dissolving the ore body using water soluble acids or alkalis and then pumping out the solution. The ore body is then recovered as a precipitate. This method is common when extracting minerals near aquifers.
