Abstract: 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.
