Along with the continuously rose of the iron ore price and the Chinese iron ore quantity demanded, Iron ore self-sufficient rate has become the bottleneck of Chinese steel industry development. In order to increase Chinese ore self-sufficiency rate, the paper study the xinjiang region low grade specularite. When the crude ore grade is 35%, the mass percent of reducing agent pulverized coal is 12%, roasting temperature is 800℃,roasting time is 50 min, milling fineness is 90% passing 0.074 mm and the magnetic induction is 84kA/m, after a low intensity magnetic separation, the iron concentrate can be got whose yield is 42.83%, grade is 62.04% and recovery is 79.26%.
