Upgradation of Barite waste to Marketable Grade Concentrate

Singh, Ratnakar and Banerjee , B and Bhattacharyya, K K and Srivastava, J P (2006) Upgradation of Barite waste to Marketable Grade Concentrate. In: Proceeding of the XXIII International Mineral Processing Congress, 2006, IMPC.



The paper presents the results of the characterisation and beneficiation studies carried out on a low grade barite sample with a view to developing technology for upgrading it to marketable product. Considering propert-ies of the barite and the associated gangues, basically two beneficiation routes i.e.well as fine size ranges gave concentrate with acceptable grade but barite recov-ery was low. Adoption of flotation process resulted in recovery over 88% with specific gravity of 4.25. The results of the bench scale studies were validated through large ,.scale trials. Based on the studies a process flow-sheet was developed for the processing of barite waste dump sample.
