De Beers heavy mineral concentrate and grain separation
De Beers heavy mineral concentrate and grain separation. Grains are processed through 2 dense media separators, dried and sieved for indicator mineral processing.
DeBeers heavy mineral concentration and grain sorting. Samples are weighed, gently milled to remove clay and vegetation, screened to greater than 2 mm, 0.3 – 2 mm, and less tha 0.3 mm. The 0.3-2 mm fraction is fed into a Mini Dense Media Separator (DMS) where minerals with a specific gravity greater than 2.9 g/cm3 are collected as a sink fraction. The light fraction is discarded. The heavy mineral concentrates are then put through a Micro DMS and minerals with a specific gravity grater than 3.15 g/cm3 were collected as a sink fraction. The heavies and lights are retained for analysis. Micro sink aliquots are dried and sieved into fractions 0.3-0.5 mm, 0.5-1.0 mm and 1.0-2.0 mm and sent for probing and analysis.
