Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver. 6. Elution Electrowinning The loaded carbon is fed into an elution column where the bullion is washed off. The barren carbon is recycled.

90% of gold can be recovered by conventional cyanide leaching. Refractory ores give low gold recoveries or give acceptable gold recoveries only with the use of signifi cantly more reagents or more complex pretreatment processes. 1 Generally, placers, quartz vein gold ores, oxidized ores, and silverrich ores are freemilling and gold can be

By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain.
