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.

Jun 16, 2013· Froth floatation 1. Froth FloatationPresented By:Gulfam Hussain 2. Introduction Floatation is an extractive process where variousminerals can be selectively extracted. Flotation is a selective process and can be used toachieve specific separations from complex ores. For example, in polymetal ores such as PbZnCu, floatation allows separate extraction of Pb, Cuand Zn.

Various process chemicals are used in the frothflotation of metallic ore of uranium, copper, zinc, lead, and iron. The flotation chemicals are mainly Isooctyl Acid Phosphate, Sodium Isopropyl Xanthate and Potassium Amyl Xanthate as conditioner and collector, MIBC as frothers, and sodium cyanide and copper sulfate as depressors.

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 53Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while

Jun 03, 2019· Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.
