De Beers Canada Exploration grain separation and sieving 0.3-0.5 mm



De Beers Canada Exploration grain separation and sieving 0.3-0.5 mm. Samples are separated using a mini dense media separator and heavy liquids (S.G. 3.2).

General Methodology:

DeBeers Canada Exploration Laboratory sample preparation for indicator mineral picking. Samples are processed using a mini dense media separator and heavy liquid (3.2 S.G.) separation. Sample weights are as follows;

(Description taken from Open File 5050)

1 Bulk Sample (kg)
2 Oversize clasts (>2 mm) (kg)
3 Wet sieve (< 2 mm) (kg)
4 0.3-2.0 mm sieve fraction (wet, kg)
5 < 0.3 sieve fraction (wet, kg)
6 0.3-0.5 mm fraction total Heavy Mineral Concentrates
7 0.3-0.5 mm Heavy Mineral Concentrates Ferromagnetic separates
8 0.3-0.5 mm Heavy Mineral Concentrates Non-Ferromagnetic separates
