摘　　要：针对湖北省某石煤钒矿,通过单因素条件试验确定"空白氧化焙烧-硫酸浸出提钒工艺"的较佳工艺参数。试验结果表明,在焙烧温度为700℃,焙烧时间1 h,硫酸用量为30%,助浸剂A用量为3%,矿物粒度-74μm 95%,浸出温度为85℃、浸出时间为2.5 h、液固比为1.5∶1的条件下,钒的浸出率可达96.30%。Single factorial tests were conducted on a certain stone coal vanadium ore in Hubei province to determine the best parameters for the‘blank roasting-sulfuric acid leaching extraction of vanadium＇process. Results of the experiments showed that under the conditions of calcination temperature of 700℃,calcination time of 1 h,amount of sulfuric acid of 30%,amount of leach aid agent of 3%,mineral particle size of 95%-74μm,leaching temperature of85 ℃,leaching time of 2. 5 h and liquid to solid ratio of 1. 5∶ 1,a 96. 30% leaching rate of vanadium could be obtained.
