Crushing Archives
“High waste dilution impacts the crushing energy needed and further increases diamond breakage risk,” TOMRA says. “Utilising TOMRA NIR technologies, we can remove non-diamond bearing material, not only improving the crushing profile of the ore, but also increasing the value of each tonne of ore processed.

Mobile screens prove their mettle in alluvial diamond
There is fertile ground for alluvial diamond mining near the present run of the Orange River, south of the town of Douglas in the Northern Cape of South Africa. In 2017 four experienced diamond miners formed a consortium under the name of Nelesco 318 to mine the elusive gemstones in the reddish earth known locally as Rooikoppie.

OVERVIEW OF DIAMOND RECOVERY TECHNIQUES
Scrubbing, crushing and screening constitute the commonly used liberation techniques, but the specific recipe, viz., the extent, the phasing and the type of process action, in each case, is dictated by the ore type and diamond occurrence. There is no standard. It, therefore, requires a good theoretical knowledge of ore dressing techniques

How Are Diamonds Mined And Extracted From the Ground
Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamond-rich depth is reached, the raw

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32 from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

mining diamond alluvial
Oct 28, 2019· 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 dry river or ocean bed.

Twenty-Five Gold Indicators You Should Know
Gold-bearing veins can consist of calcite or mostly sulfides—which often weather into iron-stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators. Iron-stained ground areas and gossans are basically another sort of color change in the ground surface.

Diamond Creaters
Because rivers meander and drainage can change, fossilizing a once active river, the search for alluvial diamonds requires some geological knowledge and a lot of luck. The process involves removing the overlying barren ground, digging up the bearing ground, extracting the diamonds, and, nowadays, restoring the landscape when finished.

Kimberlites: Earth’s Diamond Delivery System | Gems & Gemology
The diamond-bearing material at first excavated was a crumbling yellowish earth, which at a depth of about 50 feet became harder and darker, finally acquiring a slaty blue or dark green colour and a greasy feel, resembling certain varieties of serpentine. This is the well-known “blue ground” of the diamond miners.
