Bauxite Beneficiation: An Approach to Value Addition in Mining
2021.7.2 The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of...
