中文摘要: 采用流态化焙烧—酸浸工艺从某含钒石煤中提钒，考察了流态化焙烧参数和浸出参数对钒浸出率的影响。结果表明，在焙烧温度750 ℃、焙烧时间15 min、助浸剂氟化钙用量5%、硫酸体积浓度15%、浸出温度98 ℃、浸出时间6 h、液固比1.5∶1的条件下，钒的浸出率可达83.90%。
Abstract:Vanadium was extracted from stone coal by fluidization roasting and acid leaching. The effects of parameters of roasting and leaching on vanadium leaching rate were investigated. The results show that the leaching rate of vanadium is 83.90% under the optimum conditions including fluidization roasting at 750 ℃ for 15 min, dosage of leaching agent of calcium fluoride of 5%, volume concentration of sulfuric acid of 15%, leaching temperature of 98 ℃, leaching time of 6 h, and ratio of liquid to solid of 1.5∶1.
