Depressant In Froth Flotation-GOLD MINING


What is the role of depressant in froth floatation process?

In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores ZnS and Pbs , NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

Flotation Depressants - Mineral Processing and 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’s color. This is because the froth is becoming purer as

and depressant on flotation. The results were analysed using SPSS and MiniTab. Based on the F-test at 95% confidence level, the frother had no froth flotation, PGMs, flotation reagents

Flotation Conditioners -Modifiers -Activators -Depressants

This branch of chemicals will prepare the mineral surface so other reagents will be able to collect the metal. For Conditioners and Modifiers, it may be simply cleaning the surface of the particles, as in the case of removing oxidization, or it may be a chemical that these are the chemicals that bind the mineral to the air bubble to be lifted away from the waste. Activators will attach itself

Use of depressants in the direct flotation of a sili e

The batch flotation tests were carried out in a laboratory using a mechanical cell Darma, Model D-1, Sub-A, provided with a mechanical froth scrapper for the removal of the floated material and a bucket with a 3.0 L capacity.

1 Froth Flotation – Fundamental Principles

Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration

Exploration of a novel depressant polyepoxysuccinic acid for

Nickel sulfide minerals are a primary nickel source for industrial beneficiation, in which froth flotation is the main method employed Liu et al., 2018a; Yu et al., 2019; Peng et al., 2020 . The rapid depletion of high-grade ores has created a critical demand for processing low-grade nickel sulfide ores containing high quantities of various

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

The anionic flotation of fluorite from barite using

The flotation of mixed minerals confirmed that GS can be used as the efficient depressant in the anionic flotation of fluorite from barite. Zeta potential measurements and XPS results implied that the adsorption of GS on the fluorite surface was physisorption while hydrogen bonding might dominate the interaction between GS and barite surface.
