对南方某石煤钒矿进行拌酸熟化浸出,考察了矿物粒度、加水量、硫酸用量、熟化温度、熟化时间及水浸工艺参数对钒浸出的影响,并研究了H2O在熟化过程中的行为.得到最佳工艺流程和结果为:先将石煤钒矿磨至125μm以下,加10%水润湿,再加入20%浓硫酸拌匀,140℃下保温熟化3h,按液固比1.5mL/g水浸2h,钒浸出率达87.8%.石煤矿物中含钒云母结构在熟化过程中被破坏,形成难溶的SiO2,浸出液中SiO2浓度为0.09g/L,利于后续处理. The effect of mineral particle size, water addition amount, sulfuric acid dosage, aging temperature, aging time and process parameters on the leaching of vanadium was investigated. The behavior of H2O in the curing process was also studied The best technological process and results are as follows: firstly, the stone coal vanadium ore is ground down to 125μm, wetted with 10% water, then 20% concentrated sulfuric acid is added, the mixture is heated and aged at 140 ° C for 3h, / g flooding for 2h, the leaching rate of vanadium reached 87.8% .The vanadium-containing mica structure in stone coal minerals was destroyed during the ripening process to form insoluble SiO2, the concentration of SiO2 in the leachate was 0.09g / L, which is conducive to follow-up treatment.
