3.

Application/Uses

Production of marketable grade Baryte Ores

4.

Salient Technical Features including Competing Features

The technology is based on concentration of low-grade barite ore (sp. gr. 3.9) by gravity and flotation methods. The low-grade ore is upgraded to marketable grade product with sp. Gr. 4.1 .The process also enables processing of off-grade mine waste dumps for suitable industrial applications.
