Froth Crowder - 911 Metallurgist

Sep 14, 2015  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.

Flotation Froth - an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
