A New Process for Value Addition and Beneficiation of Low-Grade Baryte Ores
Implementing Organization
National Metallurgical Laboratory (NML)
Project Overview
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.
