摘　　要：对某钛冶金氯化收尘渣进行水洗无害化处理得到水洗渣;对水洗渣进行钙化焙烧,研究了焙烧温度和焙烧时间对水洗渣钒浸出率的影响。结果表明,氯化收尘渣中钒主要以低价钒形式存在;钒浸出率随焙烧温度升高而增加,焙烧温度850℃时,钒浸出率达88%;焙烧时间增加,不同产物进行二次反应,形成钒青铜等难溶化合物,出现不同价态钒酸盐相,导致在Na_(2)CO_(3)溶液中钒浸出率不同;适宜的焙烧温度为850℃,焙烧时间为120 min。The dust generated during chlorination process in recovering titanium by metallurgical process was washed with water.Then,the residue left after water-washing was subjected to calcification roasting process,and the effects of roasting temperature and roasting time on the leaching rate of vanadium from the residue were studied.The results indicate that vanadium in the dust from chlorination process mainly exists as low-valent vanadium,and the vanadium leaching rate increases with the rising temperature.The vanadium leaching rate reaches 88%with the roasting temperature of 850℃.As the roasting time increases,the previously obtained different products undergo a secondary reaction,forming insoluble compounds of vanadium bronze,and also vanadate with different valences,which results in different vanadium leaching rates in Na_(2)CO_(3) solution.It is concluded that the roasting process should be optimally at temperature of 850℃with a roasting time of 120 minutes.
