What is the role of depressant in froth floatation process?

Feb 19, 2019· 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.

What is the role of depressant in froth floatation process?

For example, sodium cyanide is a depressant used for an ore containing Z n S and P b S. N a C N forms a layer of the complex N a 2 [Z n (C N) 4 ] on the surface of Z n S and prevents it from forming a froth. Thus, it acts as a depressant. However, N a C N does not prevent P b S from forming froth and allows it to come with froth.

what is the role of depressant in froth floatation process

Apr 03, 2018· Depressants are added to prevent certain type of particles from forming the froth with the air bubbles. For example to separate zinc sulphide(ZnS) ore from lead sulphide(PbS) ore,sodium cyanide is used as adepressant which acts as adepressant for ZnS but does not prevent PbS from the formation of froth. Thus, the two ores can easily be separated.

Froth Flotation Process Detailed Explanation With

What is Froth Flotation Process? Froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth

what is the role of Depressant in froth floatation method

Depressants prevent certain type of particles from forming froth during froth floatation process. A common depressant used in the froth floatation of lead sulphide is sodium cyanide. When the ore containing ZnS and PbS is subjected to froth floatation process in the presence of NaCN, then only PbS forms the froth.

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

what is the role of collectors in froth floatation

In froth flotation the effectiveness of an air bubble to adhere to a particle is based on how hydrophobic the particle is. Hydrophobic particles have an affinity to air bubbles, leading to adsorption. Collectors are the main additives used to improve particle surfaces.

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’s color. This is because the froth is becoming purer as

ROLE OF STARCH AND METABISUPHITE ON PURE PYRITE

demands selective depression of pyrite from chalcopyrite. Conventionally sodium cyanide is used as a depressant in alkaline conditions for the selective depression of pyrite from chalcopyrite during the froth flotation process, leading to potentially disastrous environmental consequences (Ball and Rickards, 1976). Therefore,

The role of sodium sulfide in the flotation of pyrite

Apr 01, 2018· In copper-gold flotation plants, pyrite which is depressed in copper flotation is often floated subsequently with the addition of sodium sulfide (Na 2 S) to recover the associated gold.
