摘　　要：云南某尾矿经过筛分、磁选预处理后,杂质含量明显降低。利用其制备出的中间产品固态硅酸钠溶解后有一定量残渣,但经过滤后制备出的沉淀法白炭黑产品杂质含量可以满足HG/T 3061-2009标准要求。The tailings in yunnan were pretreated by sieving and magnetic separation,and the the impurity content decreased obviously.Then it was used to prepare sodium silicate.Then it was used to prepare intermediate product solid sodium silicate,which had a certain amount of residue when dissolved,but after filtering the impurity content of the precipitated silica product can meet the HG/T 3061-2009 standard requirements.
