The ore containing the precious metals should be ground fine enough to allow the maximum exposure of the gold or silver surface to the mercury (usually between 100 mesh and 325 mesh). Often, water is used as the ore is mixed with water to help disperse the ore and to promote a better precious metal to mercury interface.

Ore that has a gold grade above the cutoff grade for crushed ore is trucked from the mine or stockpiles and crushed in one of two twostage crushing circuits to a nominal size of 80% passing (P80) 40 mm. The crushed ore is hauled by a fleet of 11 trucks from the crushing plant to the VLF, a distance of approximately km.
Gold ore can resemble quartz with spotty areas of gold. According to the Environmental Protection Agency, gold is commonly mixed (alloyed) with silver and other metals. The ore may, therefore, contain sulfides like arsenic, copper, iron, and silver. The ore does not commonly have visible shiny gold on the surface.
Gold ores are classified "freemilling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory goldbearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of goldentrapment in different associated mineral phases before an .
Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.
