Abstract
In order to develop and utilise cheap iron ores with low quality for cost reduction, a hematite ore from Xinjiang province was investigated to determine the iron increase and silicon reduction using ore dressing process experiments. Results showed that iron concentrate with 61%Fe and iron recovery of 66% were achieved through the process flowsheet of grinding, high intensity magnetic separation, regrinding of coarse concentrate, clean concentration by high intensity magnetic separation, roughing reverse floatation and cleaning reverse floatation of the high intensity concentrate, with the tailings from this latter stage fed back into the roughing reverse floatation stage.
