Abstract
Porous leach pipe and method for leaching metals from mining ores. The porous pipe may be buried beneath the surface of a pile of mined ore, providing a more even and uniform distribution of the leaching solution across the pile, increasing metal yields, reducing water consumption and eliminating pooling and ponding of the solution on the top of the piles as occurs with prior art drip line emitters.
