There are several methods used including placer mining, open-pit mining, hard rock mining, and byproduct mining. Placer mining recovers gold from alluvial deposits using techniques like panning, sluicing, dredging, and cradling. Hard rock mining is used when gold is encased in rock rather than loose sediment.
Sublevel stoping mining method: • The ore body is divided vertically by driving crosscuts and haulage levels every 150 to 400ft (45 to 120m). • A collection system is constructed, during which time the stope block is all or partially undercut. • Sublevels are driven through the proposed stope block every 30 to 180ft (10 to 55m).
