Sand Washing Machine - Mineral Processing. Sand washing machine is widely used for washing materials in industries such as gravel yard, mining, building materials, transportation, chemical industry, water conservancy and hydropower, and concrete mixing station.
When materials such as sand and gravel, minerals, or tailings are below the water table or in retention ponds, mining with a cutter suction dredge is the most efficient way to obtain and hydraulically transport the materials to your processing plant.
Sand and Gravel. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.
Figure 5-5. Sand and Gravel Excavation Geologic variability in the deposit may sometimes affect sizing but more often causes a change in mineral integrity and physical properties. If a large variation exists, some products at later stages in the process may require separation.
Sand and gravel mining and processing operations include, but are not limited to, the mining or quarrying and the processing of crushed and broken stone, rock, and riprap; sand and gravel for construction or fill purposes; and sand and gravel for uses other than construction and fill. Sand and Gravel production is the largest non-fuel mineral

The clean black sand and fine gold is added to the black sand fines obtained by dredging, sniping, or sluicing for final processing at the end of the prospecting season. At the end of the prospecting year (which for me is late October or early November), I have accumulated something between 20 and 40 pounds of black sand concentrate.
