SELECTION OF MECHANICAL FLOTATION EQUIPMENT

2021-6-24  Selection of flotation equipment based predominantly on residence time is a process that ,has been taught in undergraduate university courses for many years. The residence time is typically derived from interpretation of kinetic flotation curves for targeted minerals, obtained from laboratory or pilot scale flotation testing.

Handbook of Flotation Reagents ScienceDirect

1 - Classification of Flotation Reagents. Modern classification of flotation reagents is based on the function of a particular reagent. On this basis, reagents are divided into collectors, frothers, regulators, and depressants. Collectors are a fairly large group of organic chemical compounds, which differ in chemical composition and function.
