Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form

Batch Laboratory Flotation Testing starts from the 3 fundamental types of flotation processes or methods which can be classed as either Bulk flotation Differential flotation Sequential flotation While all flotation processes are selective or differential in that one mineral or group of minerals is floated away from accompanying gangue bulk flotation generally refers to separation of

The recovery of these copper minerals by flotation or hydrometallurgy from ores typically containing 05TCu open pit mines and 12TCu underground mines is of great commercial importance

Early on the focus was on developing reagents to float complex ores which contained multiple minerals with varying flotation kinetics Often the limiting factor was not only the sluggish flotation kinetics of the minerals but the process plant’s own equipment limitations like flotation and conditioning times

Introduction to Mineral Processing In ore beneficiation flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer Sulfide and nonsulfide minerals as well as native metals are recovered by froth flotation
