Title:

Specific, Selective & Green Reagents for the Beneficiation of Ores, Minerals & Coal

Value Proposition:

Production of effective and specific surfactants/collector reagents for ores and coal in flotation technique

Summary Application:

The technology of performance of flotation greatly depends on the surfactants/collector reagents used to create hydrophobic character specific & selectively on the particle surface to be floated. Hence, development of effective and specific reagents for the ores and coal is essential.
Reagent for the beneficiation of Iron Ore Fines/Tailings by reverse flotation process. Reagent for the beneficiation of low-grade Barite and Limestone by reverse flotation process. Single reagent for the flotation of Coal fines (replacing diesel & frother).
It finds its application in value addition to low grade ores by flotation, the Beneficiation of Ores.

Advantages:
  • All the reagents are synthesized from vegetable oils and hence are completely bio-degradable.
  • All the reagents are proven successful industrially.
  • These reagents are economical & cost effective.
