1 Froth Flotation – Fundamental Principles

2009-8-27 · 1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

What is the role of depressant in froth floatation process?

2019-2-19 · 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 ...

The role of depressant in froth floatation process is to prevent certain type of materials from forming the froth with bubbles. 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. This happens because NaCN reacts with ZnS to form Na2[Zn(CN)4].4NaCN+ZnS → Na2[Zn(CN)4] + Na2S

What is the role of depressant in froth floatation process?

Depressants prevent certain types of particles from forming froth with bubbles. Due to this, we can separate two sulphide ores. For example, sodium cyanide is a depressant used for an ore containing Z nS and P bS. N aC N forms a layer of the complex N a2. ] on the surface of Z nS and prevents it from forming a froth. Thus, it acts as a depressant.

Principles of Froth Flotation | SpringerLink

For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision ...

Froth Flotation | Hazen Research

Froth flotation for separating discrete mineral particles from gangue was developed in the early 1900s and depends upon differences in the surface chemistry of the mineral species involved. At Hazen, our knowledge and experience in this field include the commonplace and the exotic. We have studied not only the flotation of sulfides, gold ores ...
