preconcentration of gold by gravity sorting


Ore sorting and pre-concentration

Bulk sorting, where loads of material (e.g. in a shovel, in a truck or a length of material on a conveyor) are directed to a destination based on measured properties; Particle sorting, where individual particles are measured by a sensor, and those that meet certain criteria are ejected into a separate bin, by an air jet or mechanical diverter.

The Pre-Concentration Of Precious And Base Metal Deposits

The grades of the worlds base metal and gold deposits are dropping. The average gold grades for the past 18 years have been 1.18 g/t from producing mines, with current undeveloped reserves averaging 0.89 g/t (Desjardins, 2014). This is a growing trend not only in gold deposits but also in base metal deposits.

Gravity concentration

gravity separation is relatively easy, the efficiency of separation decreasing as the value of the quotient decreases. The motion of a particle in a fluid is depen- dent not only on its specific gravity, but also on its size (Chapter 9); large particles will be affected more than smaller ones.

Is Ore Sorting set to replace Dense Medium Separation?

Dense medium separation (DMS) has two principal applications: the preconcentration of minerals, that is the rejection of gangue prior to grinding for final liberation, and in coal preparation to produce a commercially graded end-product, clean coal being separated from the heavier shale or high-ash coal.

Pre-Concentration by Sorting

Hand sorting of 1 to 16 pieces, formerly widely practiced at underground chutes and prior to or following first stage crushing, has greatly diminished in the United States with its high per hour labor cost, although still widely practiced in other countries and, surprisingly, in some of the most modern mills where inexpensive labor is available.
