    Heap leaching of caliche ore is carried out by the stacking of ROM (Run-Of-Mine) material, where the particle size distribution covers a wide range, from a few millimeters up to several decimeters, even diameters about 1 m. During the leaching, the multiple soluble species of caliche, which can reach total fractions larger than 40%, are dissolved at different rates, mainly controlled by their

    Heap leaching. A process to extract metals from ore, in which the mined ore is crushed and heaped onto a sculpted impermeable plastic- or clay-lined leach pad and irrigated with a leaching agent which percolates through the heap and leaches out the metals. When the “pregnant” metal-bearing leach solution reaches the impermeable base membrane, the sculpting directs it to canals from which

    Leaching on the heap is performed in 2 stages with typical solution application of 8-10 litres per m 2 per hour. The second stage pregnant leach solution passes through a 6 stage carbon circuit for gold adsorption. Gold is stripped off the carbon, electro won and calcined at the Heap Leach wet plant prior to shipment to the Lefroy Gold room for smelting.
