【 摘 要 】

Mineralogy and flotation test of a collophanite were carried out. Under the grinding fineness of -0.074 mm 78%, the phosphorus concentrate contained yield of 53.83%, grade of 35.49%, recovery of 88.12%, MgO grade of 1.22% was obtained through a closed-circuit processes of one roughing, two cleaning and one scavenging with the sulfuric acid, TF-64. The quality of phosphorus concentrate had reached the II grade of HG/T2673-95 standard.
