Diamond Mining Methods | Diamond Museum Cape Town

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 plant-life.

1995-3-1 · Alluvial diamond mining in the region dates back to at least 1904 (Marshall, 1986, 1987a). More than two million carats of diamonds were recovered up to 1984 by artisanal miners washing the alluvial gravels of this field. The alluvial diamonds found in the region have not been linked to any known primary source rocks.

How Are Diamonds Mined And Extracted From the Ground

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamond
