depressants in mineral processing

Depressants | Solvay

Mineral processing; Depressants Depressants. Depressants make it possible to increase final recovery consistently without sacrificing concentrate grade. They can either depress the effect of hydrophobic gangue minerals in the ore that would otherwise report with the froth along with the desired mineral, or hold down the desired mineral

Flotation Depressants Mineral Processing & Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral

Flotation Depressants | ArrMaz

Depressants are often used to increase the efficiency of the flotation process by selectively inhibiting the interaction of one mineral with the collector, for example, the depression of quartzite to allow for more optimal apatite/collector interaction, thus improving final recovery and grade.

Role of Collectors and Depressants in Mineral Flotation: A

A theoretical analysis was conducted to study the role of collectors and depressants in flotation, based on the extended Derjaguin–Landau–Verwey–Overbeek (DLVO) theory, where the hydrophobic force is considered. The collector-coated hydrophilic particle and the depressant-coated hydrophobic particle are simplified to a sphere uniformly covered with respectively hydrophobic and

Use of depressants in the direct flotation of a silicate

1. Introduction. Flotation is the most common concentration process used by the mineral industry, both in quantity of ores processed and in diversity of applications (Peres et al, 2007).At present, over 2 x 10 9 t per year of ore is estimated to be processed through flotation. In Brazil, this technique played an important role in the growth of the mineral sector, especially in the industry of
