When using a conventional flotation reagent scheme and flowsheet, only a few of these ores respond (i.e. lime + NaCN + collector), giving extremely poor metallurgical results. The majority of these ores require a specific treatment process to achieve satisfactory metallurgical results.

What is the role of depressant in froth floatation

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.

Froth Flotation Process Detailed Explanation With

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 layer.

Common Questions About Froth Flotation Process

2019-4-17  Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.>
