Flotation reagents are chemicals used in the mineral flotation process that can modify mineral surface properties and improve or reduce the hydrophobicity of minerals, and thereby, the pulp properties and froth stability are more conducive to the separation of minerals [3,4,5,6,7].They are usually divided into the activator, collector, …Web
Attachment of particles and droplets to bubbles—the latter being of various fine sizes and created by different techniques (as described in detail)—forms the basis of flotation, a process which indeed was originated from mineral processing.
