25/04/2018· 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. Since then, heap leaching has been adopted successfully by many mines across the world. Heap leaching
leach pad with a stacked and leached ore heap in the background is shown on Photo 2. Each ore lift surface is wetted uniformly during leaching by using irrigation drip emitters or sprinkler sprays. Leaching is generally conducted in 30 to 120 day or longer leach cycles with barren or recirculated alkaline gold and silver or acidic copper process solutions. The maximum rock size of the

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the leach cycle, generally takes from one or two months for simple oxide ores e.g. mo
Gold heap leaching is a process to pile gold bearing ore crushed to a certain particle size on a water tight site, then spray the cyanide solution on the ore pile, making it leaching through the gold ore to extract gold. Gold heap leaching process

There are 10 main factors affecting gold heap leaching efficiency. 1. Ore Properties. Gold ore with loose structure and large gaps has good permeability, which is beneficial to theration and diffusion of cyanide solution inside the ore. The gold in the ore can fully react with the cyanide solution, so the gold leaching speed is faster. Conversely, if the structure of the ore is
