摘　　要：针对石煤钒矿酸浸液中硅含量高的特点,采用非离子型絮凝剂将溶液中的SiO2进行絮凝沉淀,同时对溶液进行净化,得到除硅后的含钒酸性溶液,过程中钒损失率<1%。然后将得到的SiO2沉淀进行洗涤、干燥、煅烧,可制备出SiO2含量为94.32%、比表面积为265m2/g、吸油值为2.62mL/g的白炭黑产品,产品主要性能指标符合HG/T 3061-2009沉淀水合二氧化硅的技术要求。According to the characteristics of the high content of silicon in the acid leaching solution of the stone coal vanadium ore,the silicon was removed by flocculation and sedimentation by using non-ionic flocculant. In the process, the loss rate of vanadium was less than 1%. Then through the process of washing, drying and calcining, the white carbon black products with the SiO2 content of 94.32% ,the specific surface area of 265m2/g and the oil ab- sorption value of 2.62mL/g were prepared. The main performance indexes were accorded with the national standard of HG/T 3061-2009 for the precipitation of hydrated silica.
