A New Process for Value Addtional and Beneficiation of Low Grade Baryte Ores

Use of low grade barium containing ores

The technology developed is for beneficiating of rejected low and lean grade baryte ores and the concentrate so produced is useful for oil drilling, barite chemical and other applications. While mining the barite high grade variety of above 4.1 to 4.35 sp.gr are taken separately for direct use after grinding. But the low grade below 3.9 sp. gr. is rejected. These low grade samples were processed for value addition. The process so developed basically involves crushing, classification, pre-concentration through jigging when material sp. gr. is expected to be 4.1. When sp.gr. of more than 4.1 is required, the sample is subjected to flotation after grinding.

• Utilizes low grade ore, rejected part of barium extraction-tailing
• Can work with below 3.9 gram specific gravity ores also
• Process can be modified on case to case basis
• Various gangue and impurity materials can be removed using combination of crushing, grinding, jigging, classification, gravity separation, flotation, dewatering
