Basic principles of alluvial diamond exploration

Outlining and evaluating an alluvial diamond deposit Evaluation of an alluvial diamond deposit requires rigorous geological control from the outset. This includes shallow drilling, pit excavation and the con- centrating of diamond from gravel by using jigs in water, or by dense medium separation.

Mobile screens prove their mettle in alluvial diamond mines

Alluvial diamonds from as far as the present-day Jagersfontein and Koffiefontein were pushed into the surrounding areas as the river flooded the plain en route to joining the Vaal River further downstream. This is where Schalk Steyn of Steyn Diamante, doyen of alluvial diamond mining in South Africa, established one of his mining operations in

The first diamond found in South Africa came from an alluvial deposit. Alluvial mining is the world's main source of diamonds, accounting for 40 percent of the world's total diamond reserves, but 70 percent of its production. Many primary mines are found by tracing back the placer deposits. 1. River alluvial deposit

Diamond Exploration Botswana Diamonds

DIAMOND EXPLORATION. Diamond discoveries can take various forms, mainly kimberlites, but also lamproites and alluvial/paleo-placer deposits. Kimberlite is a type of potassic volcanic rock best known for sometimes containing diamonds.It is named after the town of Kimberley in South Africa, where the discovery of an 83.5-carat (16.7 g) diamond in 1871 spawned a diamond

Processing Zimbabwe Consolidated Diamond Company

The screening process is done for both alluvial and conglomerate. Alluvial screening is done to remove excessive fines content and oversize material. The resultant product is alluvial diamond concentrate with required particle sizes; Conglomerate screening is done to remove fines and oversize material.

Mineral processing Alrosa

This light is detected by an X-ray recovery unit, which then separates the diamond-containing material from the process stream. This concentrate is sent on to the refinement section. We use XRL recovery units of LS-20-05, LSD-20-04, and LSD-4-03 series. *Gravity concentration (jig separation) Diamonds are heavy minerals.

Diamond Mining Methods Pipe Mining Alluvial Mining

Instead, huge rocks that are full of diamonds are brought out of the mine and moved to a screening plant for separation. To find one small diamond, often over two hundred tonnes of ore must be mined. Natural diamonds are truly rare. Alluvial Mining method. The Alluvial mining method is done in riverbeds and on beaches.
