#0183;#32;Traditional gold processing methods generally use the toxic chemicals cyanide or mercury as reagents to extract gold particles from ore, exposing miners and the environment to toxic waste and gases. In contrast, Clean Mining offers an environmentallysound gold processing technology that uses an inorganic compound, thiosulphate, in the place of toxic chemicals.
In the second part of this 3part series, we explore further the various life cycle mining stages at Eldorado Gold. Construction (35 years) Once a projects environmental impact assessment (EIA) and other permits are approved by relevant government authorities, and we have received a positive decision from our Board of Directors to proceed, our Capital Projects team can begin construction.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
