description The invention relates to a method for comprehensively utilizing a byproduct silicon slag in a production process of preparing hydrogen fluoride from fluosilicic acid, which specifically comprises the following steps: by taking the byproduct silicon slag in the hydrogen fluoride production process as a raw material, selectively dispersing and settling under the action of a dispersing agent and an auxiliary agent, centrifugally drying an emulsion formed by dispersing silicon dioxide, and recovering SiO2 in the silicon slag as a white carbon black product. The filtrate can be recycled and reused as a dispersing agent after being concentrated; the recovery rate of effective components in the silicon slag is gt; the operation process is simple, solid waste emission in the production process is effectively reduced, waste is turned into wealth, and the method is green and environmentally friendly. 本发明涉及氟硅酸制备氟化氢生产过程中副产硅渣综合利用的方法，具体是以氟化氢生产过程中副产的硅渣为原料，在分散剂及助剂的作用下选择性的分散沉降，对二氧化硅分散形成的乳液进行离心干燥回收硅渣中的SiO2作为白炭黑产品，滤液经浓缩可作为分散剂回收
