Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...

In view of this, a simple mobile plant is assumed to be the best alternative to economically process tailings and marginal gold resources. The setting of plant depends on appropriate process flow sheet for gold extraction. Therefore, there is a need to design a process that fit a simple mobile concentrator plant to extract gold from tailings. 1.3.

1. Introduction. In the 19th century, cyanide leaching was proposed, and then it was widely used in gold processing due to its advantages of maturity, low-cost and high-leaching efficiency (Li et al., 2020).Around the world, about 90% of gold is recovered by this method (Acar, 2016; Tu et al., 2019), thereby resulting in the production of …

Here, the material is pumped to a processing plant to extract the gold. "This operation is much more cost-effective compared to a truck and shovel operation, due to the use of slurry transport. However, the majority of the tailings are stored together with process water, which makes hydraulic monitoring of dry heaps impossible."
