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.

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.

People used to float -0.5mm coal in flotation cells in 1960s,70s and 80s, but now they have switched to -0.25mm flotation. It is recommended that maximum size particle that you try to float be 0.3mm. The reason is that 0.5mmx0.25mm flotation requires more residence time than 0.25mmx0 flotation.
