ing, heap leaching, and iron precipitation tech-niques that continued to be used at Rio Tinto into the 20th century. In Britain, copper and tin were worked in Corn-wall and traded with the Phoenicians as early as 1500 B.C. The Remans brought improved metal-lurgical techniques to Britain, and spurred devel-
Heap Leach Mining Systems . This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g., most gold ores) to two years (for nickel laterite ores). The leach solution containing the dissolved minerals is then collected, treated in a process plant to recover the target mineral and in some cases ...
Jul 11, 2018· Heap leaching can take anything from a couple of months to several years. In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70% compared with 90% recovery in an agitated leach plant.
In the United States, for example, the energy requirement for SX/EW processing of heap or dump leaching ranges from an estimated 10 MJ/kg to 25 MJ/kg - the difference being largely the pumping costs. In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant.
heap leaching: Generally, an industrial mining process in which a valuable metal is extracted from a heap, or pile, of crushed ore. For copper oxide ore, heap leaching is the first stage in the process of hydrometallurgy, in which a chemical solution is applied to a heap of crushed ore, through which it percolates, dissolving the copper.
