摘　　要：研究了澳大利亚SINO铁精矿的物理、化学性质,并对该铁精矿进行了提铁降杂精选磁选试验。在控制磁场强度1 400Oe;选别磁场强度1 300Oe,给矿量60kg/h,溢流量1 044L/h,底流量46.8L/h的条件下,可获得品位69.38%,回收率95.72%的精矿产品。Physical and chemical properties of iron concentrates in SINO Iron Project in Australia are studied and magnetic separation tests of concentrates to improve ore quality and reduce impurity are conducted. Under the condition that intensity of controlling magnetic field is 1 400 Oe, intensity of separation magnetic field is 1 3000e, ore feed is 60 kg/h, overflow rate is 1 044L/h and underflow rate is 46.8L/h, concentrates with 69.38% grade and 95.72% recovery can be obtained.
