Basic principles of alluvial diamond exploration

01-03-1995· 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.

ALLUVIAL DIAMOND MINING Lucapa Diamond Company

The 1.1 Mtpa Lulo diamond plant includes XRT large-diamond recovery technology capable of recovering individual diamonds of up to 1,100 carats. Alluvial mining and exploration activities at Lulo have until recently been focused primarily on the terrace deposits along a ~50km stretch of the Cacuilo River running through the ~3,000km2 concession, much of which remains untested.

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.
