heap leaching leached Solutions Just Right For You

Heap leaching has become a popular method of extracting gold writes Nicolaas C Steenkamp and Leon Louw Heap leaching is used to extract gold copper silver uranium and iodine This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s and then by several gold mines in the western parts of the US a few years later Heap leaching is a low capital cost alternative to conventional processing techniques for gold recovery from areas that contain small gold particles in a porous host rock For successful heap leaching the ores to be leached must maintain good permeability after being stacked into heaps so that the leach solutions can percolate evenly through them
