The ore process property is the basis of beneficiation technique. By making studies of process mineralogy of a certain medium grade simatic phosphate rock based on identifying mineral composition,ore texture and structure, minerals disseminated relationship and process size, the article puts forward a feasibility of the single reverse flotation. According to the technical indexes obtained in practice of the single reverse flotation of the phosphate rock,the article estimates the technical and economic indexes of simatic phosphate rock single reverse flotation,and requires strengthening technology in the dressing process.%矿石工艺性质是选矿工艺实现的物质基础.本文通过某中品位硅镁质磷块岩工艺矿物学研究,在查明矿石物质组成基础上,通过矿石结构构造、矿物空间嵌布关系和工艺粒度研究,提出矿石单一反浮选的可行性.并根据磷块岩单一反浮选生产实践的技术指标,计算该硅镁质磷块岩单一反浮选可能获得的技术经济指标,以及选矿工艺中需要加强的技术环节.
