Heap Leaching

Mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals. Sprinklers, or frequently drip irrigation, are used to minimise evaporation. The solution then percolates through the heap and leaches out the precious metal. This can take many weeks. The leach solution having the dissolved metals is then accumulated.

Professional Pump Services have been supplying drip tube to the mining industry for many years.
