Gravimetric Concentration & Gold Pelletmetry

To get an optimal recuperation in the processing of the minerals of the placer type in the plant of treatment, for whatever of the methods to be selected, the following parameters will be controlled:

Gravel Pelletmetry
The study of pelletmetry of auriferous gravel present in the alluvial bank is fundamental for selecting the type of classifier between thick and thin.

Specific Gravel Gravity
it is very important to determine this element, for the effects of metallurgical balance, despite the fact that to determine the ratio it is not adequate to express it in tons, because the laws of a deposit of alluvial gold normally are used in Grs.Au/m3, but not in Grs. Au/T.M.

Gold Pelletmetry
it is important to have the full knowledge of the pelletmetry of metallic gold that varies in size from one area to another, being that while one leaves the area of its origin it tends to become into microscopic gold and its recuperation requires a much more advanced technology, above all in the porous and laminated gold in a microscopic state acquires the tendency to reject water (hydrophobic property). The particles of gold from under the Corey Factor (0.15) tend to float, hereby, its recuperation by the conventional methods of gravimetric is almost none.

Corey Factor: Fc = t + 1 x w, where t is the thickness; l, the length; and w, is the width.
