It has been shown that acid heap leaching has been used in Spain since 1700 for copper. The first gold heap leach is attributed to the Cortez Project in Nevada in 1969, but in 1967 over 200,000 tons of copper was recovered from leach dumps. The first copper dump leach can be traced back to 1921.

Ore-Max Best Practice Drip Systems For Heap Leach

Oxygen is an essential element in the leaching process. Efficient heap leach operations require that oxygen plus the acid or biological agent be present to dissolve the mineral deposits into the leach solution. In general, the higher the oxygen level, the greater the mineral recovery. Applying too much leach solution saturates the crushed ore and drives out the oxygen.
