What is the role of flotation froth in the flotation process

These froths play a very important role in the froth flotation process Just because of these froths that the ore particles or ore powder can be attached to the sticky froth then these froths carry the ore particles out of the slurry and reach the washing stage for removing the ore particles Finally the concentrate is obtained and the whole


At the end of the froth flotation process 2 streams were formed The 1 st stream being the pregnant solution and the 2 nd being the waste material which were both in the form of a slurry

Recovering Gold through the Froth Flotation Process

Feb 06 2018 Along with mechanized mining equipment froth flotation dramatically improved the efficiency of gold mines Thanks to this process miners and refiners are able to extract quality minerals from ore at lower grades than has been previously possible making it perhaps the most important mining industry innovation of the 20th century


or less stable and mobile layer of froth will persist on the surface of the slurry which will gather and recover a proportion of the adhering mineral particles 81 A Kinetic Approach to Flotation Modeling Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process


FLOTATION PROCESS FOR MORE EFFICIENT COAL RECOVERY Froth flotation is a widely used cost effective particle separation process However its high performance is limited to a narrow particle size range eg between 50 m and 600 m for coal and between 10 m and 100 m for minerals Outside this range the
