Gold processing - Mining and concentrating Britannica www.britannica.com technology gold-processingWhen gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content i.e., greater than 20 grams of gold per ton of ore , cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. Gold processing Britannica www.britannica.com technology gold-processingThe 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 gold-silver 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. Extracting Gold HowStuffWorks science.howstuffworks.com gold4Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. An Overview of Basic Gold Separation Methods raregoldnuggets.com Panning is a gold mining method that uses water to separate the heavy gold particles from the lighter materials in the ore.
