How to SIZE a Sluice Box - 911 Metallurgist

Jul 29, 2015  Slope of a sluice is generally in the range of 1.3 cm (1/2 in.) to 3.8 cm (1-1/2 in.) per 30.5 cm (1 ft), depending on the size rock in the feed. To move the larger rocks down the sluice requires a steeper slope or more water, both of which cause greater gold

Material Particle Size Classification Equipment

In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones. Since classification is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant pumps. It is relatively ...

Equipment Selection for Surface Mining: A Review

The process for creating a borrow-pit is sequential: rst explosives loosen the earth; then, exca-vating equipment removes small vertical layers (or benches) of material, as illustrated in Figure 1. Over time, these benches themselves are blasted, excavated and removed, making the borrow-pit wider and deeper.
