Get PriceThe gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. 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 .
Get PriceOnly a few minerals are important as gold carriers. Native gold is by far the most important, followed by gold tellurides. Other gold compounds are economically irrelevant. There is a series of minerals that can carry gold as a physical constituent such as pyrite and arsenopyrite. The mineralogy determines the recovery process of gold.
Get PriceTreatment methods for the recovery of gold from goldbearing ores depend on various factors, such as the mode of occurrence of the gold and associated minerals and the grade of gold in the ore.
