gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. however, froth flotation processes may also be used to concentrate the g. in some cases, particularly when the g is present in the ore as discrete coarse particles, a gravity concentrate can be directly smeltedto for · text under ccbysa licenseextractive metallurgy extraction process of g (au) andgenerally, extraction process of all metal always include the comminution (size reduction)to liberate achieve mineral. the next process of g extraction from hydrometallurgy route is leaching. there are reagents that can be used to g leaching process mercury (hg), cyanide (cn) usual as kcn or nacn, thiosulphate (na2s2o3), and thiourea.how cyanide leaching is used in g miningjul 03, · of those methods, the cyanide leaching process (cyanidation), is the method that is commonly used the most often to do this. as the name implies, the main component in the process is a sodium cyanide solution. this article will give a general overview about how this important, 1 g mining process works.
