Read MoreThe yields and flotation rate constants for the flotation of coal were obtained by fitting a first-order kinetic model (Wills and Finch, 2016), which follows: 2 R = R m a x (1 − e − k t) where R is the yield (i.e. recovery), R max is the maximum yield (i.e. maximum recovery), k is the flotation rate constant, and t

Read More2019-10-18 Froth flotation process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. The froth flotation process is to grind the mineral to the floating requirement, adjust the pulp concentration and add the flotation reagents, then inflate the air to make the mineralized froth separate.

The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
