3. Under the condition of a large jig room, a small stroke, and insufficient water drum power, the gold mineral jig is losing the normal working function because of the piling up layer bed. 4. Make sure that the required pressure and sufficient amount of water are added to the Jig, especially in the dry season.

Circular jigs have not been generally accepted in gold mining, probably because of their high cost, large capacities, and low (20:1) recovery ratios that were developed for the offshore tin industry. The concentration of free gold in a gold placer is very small and a high concentration ratio is required to make an economic concentrate.

Barrick Gold Corporation has one of the largest openpit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground.
