2019. 10. 28. Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds. Miners build walls or divert rivers to expose the diamond-bearing

The techniques used will not be the same between artisanal and industrial mining, however there are some common elements: Crushing, not too fine (rough diamond must not be crushed). Screening separates the sand from large elements.
get priceOnce a diamond operation yields ore, the diamonds must be sorted from the other materials. Excavated ore is transported to a processing plant. The kimberlite is first crushed and then processed through the plant, which consists of a series of screens, jigs and scrubbers and a gravity pan or DMS plant to remove lighter particles and create a concentrate of heavy material, which includes the
