1. Uses of Flotation Agents, and it’s short
classification
Flotation Reagent is the type of agent that is used in the process of mineral flotation, it adjusts
the behaviour of flotation of minerals and helps achieve a good effect of separation of
minerals.
Type of Flotation Agents
There are three types of flotation agents namely, flotation collectors, flotation conditioners
and flotation frothers.
 Flotation Collectors
The main function that a flotation collector performs is of changing the hydrophilicity of a
mineral surface. Basically, flotation collectors enhance the hydrophilicity and further increase
the adhesion of a particular mineral on the bubble, which makes minerals more floatable.
Mostly, all minerals are hydrophilic by nature, flotation collectors are used as a king of a
flotation reagent. The most widely used flotation agents are xanthate and dithiophosphate.

2.  Flotation conditioners
The function that Flotation conditioners perform are of adjusting interaction between
collector and minerals, they also adjust the pH levels and also promotes the floatability of the
minerals. Flotation conditioners are of the following categories- pH categories, inhibitors,
activators, dispersants and more. pH modifiers adjust the value of pH in the flotation slurry.
Activators are reagents which help enhance the floatability of minerals in the process of
flotation, they change the composition of mineral surface and even further enhance the effect
of the collector. Widely used activates as flotation conditioners are sulphuric acid, copper
sulphate, sulphurous acid, sodium sulfide and more. Inhibitors are reagents that increase the
hydrophilicity of minerals and form a film that is hydrophilic in nature. The film is formed on
the surface of the particles of ore. Dispersant is a reagent that does not allow fine minerals to
aggregate. Some dispersants that are used commonly are phosphate and sodium silicate.
Dispersants are flotation agents for phosphates.
 Flotation Frothers
Their primary function is to promote formation of uniform bubbles as well as to enhance the
elasticity of the surface of the bubble. They also make the bubbles more stable and does not
let them get deformed as easily. Widely used flotation frothers are pine oil and MIBC (methyl
isobutyl carbinol).
A regular method used for elimination of carbonates from other sedimentary minerals is
reverse flotation. In this process, phosphate minerals are removed by depression and
carbonate minerals float. Fertiliser coating material used for flotation agents is elemental
sulfur.
