| Abstract: | The paper studied the semi - industrial test of extracting Vanadium pentoxide by the pelletization-rotary kiln roasting - low acid leaching-ion exchange technology from the Vanadium-containing kaolin. The experiment results indicated the vanadium conversion rate achieved above 74% in the rotary kiln roasting process,the Vanadium pentoxide recovery of the entire flow reached 71.82% and the product quality met the national standard GB-3283 requirements. |
