Adjustable emitter for heap leach mining percolation

mining is typically employed in conjunction with low grade that is normally pre-crushed to suitable size and then treated with a solution lixiviation, such as an aqueous solution of sodium cyanide, potassium cyanide, acidothiourea, ammoniacal thiosulfate or malononitrile in the case of

Heap Leaching - an overview | ScienceDirect Topics

For heap leaching, the is subjected to size reduction by crushing before stacking on impermeable under liner fitted pads. If the ore is very permeable, little or no crushing may be required, Lixiviant contact with the mineral particles needs to be ensured through efficient percolation. Percolation rate should be slow enough to facilitate necessary contact periods between the ore particles and the
