Entrainment of Gangue Minerals in Froth Flotation
Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …

Froth Crowder
The concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells.. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder plate is Piece/Item # 12 on the drawings below.

Effect of Collector & Frother Concentration on Copper Flotation
A high frother concentration produces an excessive amount of froth in the flotation cell. This increases the froth overflow and flotation rate, but, unfortunately it also decreases the concentrate grade. Collector concentration has a significant effect (either linear or non-linear) on all three quantitative response variables.
