Beneficiation of barite: A review of processing studies at CANMET

The beneficiation of barite has been the subject of many investigations at CANMET, thus reflecting barite's importance as an industrial mineral. Fifty-one studies relating to various aspects of beneficiation were conducted between 1920 and 1986, and a review of some of the more important studies is presented. The information, including mineralogy, beneficiation methods and results, flotation parameters, and reagent concentration data, is presented in tabular form. By so arranging the principal data, the research worker and production metallurgist will be assisted in the evaluation of barite ores from a variety of origins.
