摘要
石煤中加入石灰和适量的添加剂焙烧,焙砂用NH4HCO3和NaHCO3溶液浸出,浸出液经离子交换树脂吸附,可制得纯度达到国标99级以上的V2O5。在焙烧过程中解决了传统钠化焙烧的废气污染问题,经交换吸附后的废水可直接回用于浸出,不影响浸出率和产品质量。
CaO and some additives was added to the stone coal when it was roasted and then the calcine was leached in NH4 HCO3 and Nail exchange absorb process of the method, this method solved the the absorb process can be direc and quality of product. CO3 solution. The V2O3 which purity is above 99% was got from the ionleached solution. Compared with conventional roasting-sodium oxidization pollution of the waste gas and wastewater, the wastewater discharged from tly reused into the leaching process without any effect on the leaching rate and quality of product.
