This flowsheet is typical for small to medium tonnages of alluvial feed (5 to 30 tons per hour). Such material is often cemented and requires crushing by either jaw or gyratory crushers.
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.
Low Grades. The grade of a diamond deposit is the estimated number of carats contained in one hundred tonnes (cpht) or hundred cubic metres (ct/100 m 3) of gravel.Some alluvial deposits have grades measured in carats per cubic metre/tonne and marine deposits along the South African/Namibian West Coast are often measured in …

To assess these models, we conducted a study of the provenance of heavy minerals from Kalimantan's Cempaka alluvial diamond deposit. This involved collecting U–Pb isotopic data, fission track and trace element geochemistry of zircon as well as major element geochemical data of spinels and morphological descriptions of zircon and …
The alluvial diamonds found alongside the inland rivers were trapped in gravels derived from the Karoo floor and the Dwyka tillite. When the ice sheet retreated, diamonds derived from the pre ...
These alluvial diamonds are recovered by placer and marine mining techniques that are very different from hard-rock kimberlite mining. Although these specimens are found "off-craton," they derive from "on-craton" kimberlites and are thus formed by those processes. Figure 5. Seismic waves can illuminate the presence of mantle keels ...
