Mining diamonds with specialised tools. we use advanced diamond mining technology and huge earth-moving equipment to bring diamonds to the surface. in our open-pit mines, trucks with 250 tonne payloads and tyres twice as tall as an average man carry diamond-rich
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.
Alluvial diamond resources. a similar assessment was also conducted by the u.s. geological survey usgs in liberia wahl and others, 2007. the usgs assessment made sub-stantial contributions to the assessment process of the diamond potential and contributed to a lifting of the sanctions on mining and selling of diamonds imposed on liberia through
Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery. these systems are based on the property of diamonds having a much higher specific gravity density of 3.52 gcm3 compared to most of the other minerals that make up material in which diamonds are found.

Alluvial mining for diamonds started in india and for centuries alluvial mining was the primary source of diamonds. hard rock mining of primary kimberlite on an industrial scale had only emerged with diamond discoveries in south africa in the 19th century. initially, kimberlite pipes were mined as open
Mining methods depend primarily on the degree of cementation of the rock. in some deposits, blasting is required to loosen the material prior to processing. the material may undergo primary crushing at the mine site before being transported to the processing plant. figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing.

In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. compared to alluvial mining, the post-processing is shorter and is a less resource-consuming task as diamonds are identified in situ of the work area. offshore marine diamond mining
The diamonds in the yellow ground can be washed into streams to eventually wind up in alluvial deposits. eventually some diamonds are washed off the landcontinents into the sea as in namibia. diamonds in the primary rock kimberlite are found by a variety of techniques, but of great importance is the use of sampling for indicator minerals.
