Heap leaching is abbreviated as heap leaching, and the main process principle is that a solution is used for infiltration in a ore heap, and metal substances in the ore are selectively dissolved and leached through capillary and molecular diffusion. Heap leaching is mainly divided into two types, namely, waste rock heap leaching and off-surface ore heap leaching: the heap leaching ore of the former is not broken, the scale is large and can reach more than million tons, and the leaching time is as long as several years; the latter heap leached ore is generally crushed to 5 to 20mm, on a smaller scale, with leaching times of only a few months. The general heap leaching process includes constructing waterproof base pad, building ore heap on the base pad, and spraying the leaching liquid regularly with nozzle. The heap height depends on the ore type, nature, for example: gold ore 3-6 m, copper oxide ore 5-6 m, sulfur-containing mineral up to 15m. The investment and the operation cost of the method are low, and the leaching rate is generally 60-80%. In the heap leaching process tests or productions, because the leach solution is formulated with dilute hydrochloric or sulfuric acid, it reacts with silicate in the ore to form silica gel during heap leaching. These silica gels can settle to the bottom of the column or flow with the leaching liquor into the post-heap acid recycle tank and settle to the bottom of the tank, resulting in the column and post-heap acid recycle tank having to be manually cleaned frequently.
