Flotation Reagent | Article about Flotation Reagent by The ...

When a regulating agent acts directly on a mineral surface, making possible better adherence of the collector to the mineral and activating flotation, it is called an activator. For example, the addition of sodium sulfate sulfidizes the surface of oxidized nonferrous metal minerals and permits the adherence of xanthogenate molecules to the mineral.

Flotation Principles - Mineral Processing & Metallurgy

Flotation Principles. Flotation, in its latest phase, is a process of concentrating ores by frothing. When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed. This froth, rising to the surface of the liquid mixture, is laden with sulphides or other ...
