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 ...

Early investigations have shown that the relationship between gold grades and production costs is complex (De Assuncao, 2013), with these studies questioning whether clear relationships even exist, particularly at an industry-wide scale (Kanakis, 2014, Ulrich et al., 2016) where the individual mine grade-cost relationships are 'hidden' by …
If an average electricity cost saving of 5% is extrapolated across the South African gold processing industry, the potential cost savings amount to R 25-million per annum. Although the costs saving opportunities are feasible, it is influenced by the reliability of the equipment and the dynamics of ore supply.
Thomas (2018), as part of the cost analysis done for Hydrogenics, estimated the price of a MW-scale PEM electrolysis system to be around $1,000/kW by 2030, and $550/kW by 2050. This price, however, can be reduced to $700/kW and $385/kW for multi-MW system in 2030 and 2050, respectively.
