alluvial mining machinery techniques

A variety of alluvial mining techniques were used over this time but all relied on the same premise using water to wash goldbearing sediment When this goldbearing sediment is loose gravel for example separation is easy However such deposits tend to have low gold concentrations

The first diamonds discovered in South Africa were from alluvial deposits Today industrial alluvial mining involves building a large wall to collect the water in one area Diamonds are often found in the gravel layer which collects under layers of other material such as mud clay and underwater plantlife
