- Abstract
The preparation of inorganic brown pigment from red mud is investigated. The results of the phase and chemical analyses of raw material and the product are given. A flow diagram is proposed and the parameters of the pigment production are recommended. This approach has provided a pigment of pure color with the opacity of 8 to 10 g m-2 from red mud (up to 80%) without additives and the reduction of Fe(III) into Fe(II) using sulfide sulfur.
