Artisanal and Small-Scale Gold Mining Without

Gold concentrate is combined with a flux, such as borax or other materials of mixtures, in the crucible. The flux acts to decrease the melting temperature and viscosity of non-gold minerals in the concentrate so they are more easily separated from the gold during the cooling process. Small amounts of concentrates, usually around 50 to 100 grams, are used in direct smelting. Concentrate and flux are

Filtration - Wikipedia

Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated. Filtration, as a physical operation is very important in chemistry for the separation of materials of different chemical composition.
