This is an article in the field of metallurgical engineering. The vanadium ore with vanadium containing sericite and illite in Shaanxi province was taken as the research object, low-temperature sulfuric acid ripening-water leaching process was used to extract vanadium. The effects of ripening temperature, ripening time, sulfuric acid dosage, sodium chloride dosage, leaching temperature, leaching time and liquid-solid ratio on vanadium leaching rate were investigated. The results show when 25% sulfuric acid and 0.8% sodium chloride are added to the stone coal vanadium ore, the sample is aged at 130 ℃ for 8 h, and the sample is leached at 55 ℃ for 2 h under the conditions of liquid-solid ratio of 1.5∶1, the vanadium leaching rate can reach more than 89%. This indicates that it is feasible to adopt low temperature sulfuric acid ripening and water leaching process to extract stone coal type vanadium ore. |
