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

Which of the following involve the froth flotation process?

The process of froth flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate. In this method of mineral processing, the ores contain multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation.

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

Flotation Froth - an overview | ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
