Froth floatation - SlideShare

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 poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cuand Zn.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Nov 01, 1999  1.. IntroductionEvaluation of the froth flotation process is not new. The ‘Release’ analysis procedure was developed by Dell in the UK in the early 1960s, a development from the froth flotation of metallurgical slurries. The ‘Tree’ analysis technique was developed by Nicol in Australia in the early 1980s, a method especially developed for coal flotation.
