Floatation

Jan 30, 2015· REVERSE FLOTATION- in which the gangue is attached to the froth and minerals remain in tailing 5 6 BASIC PRINCIPLES This process commences with Comminution (to increase the surface area of the ore) The ore is ground to fine powder and wetted with water to form a Slurry A Surfactant chemical (known as COLLECTOR) is mixed with slurry to ....

Impurity Removal in the Reverse Flotation of Iron Ore

Whilst this flotation process has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss In 2010, CSIRO investigated the use of a reverse anionic flotation process for Vale iron ore Batch laboratory flotation studies conducted on Vale samples showed significantly reduced reagent costs and ....

Dissolved Air/Gas Flotation Separators

Dissolved Air Flotation (DAF) System : Dissolved Air Flotation (DAF) is a Physio-Chemical Treatment where air is intimately contacted with an aqueous stream at high pressure, dissolving the airThe pressure on the liquid is reduced through a back pressure valve, thereby releasing micron-sized bubbles that sweep suspended solids and oil from the polluted stream to the surface of the air ....
