| Abstract: | Production of phosphoric acid from phosporus ores in a rotary kiln offers the advantages such as high availability of raw materials and low production cost due to little consumption of electricity and dispensing with sulfuric acid. In this paper the effects of gangues (e. g. SiO_2. Al_2O_3. CaO. MgO. Fe) in phosphorus ores and amenabilities of different ores to the production process are studied. The experimental data and the results of electron probe analyses are presented. |
