Flotation Chemicals | İnhedron

Flotation Chemicals. It is a weak foamer (frother) that is most commonly used in mineral flotation, forming brittle foam. Since it is a neutral foamer, it works in both acidic and basic pulp. It is especially suitable for use in high volume enterprises where fine particle size lead-zinc sulphides are processed.

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.
