Abstract

Abstract

The tailings from the dressing plant of JISCO contains about 25% iron,which has a high recovery value.Iron mainly exists in form of Hem-limoniteOre,and some of them in siderite and magnetite in this tailings.In this paper,the process of magnetizing roast-low intensity magnetic separation and high intensity magnetic separation-magnetizing roast-low intensity magnetic separation were investigated with semi coke as the reductant in order to recover the iron lost in the tailings.The experimental results indicate that the iron concentrate with iron grade of 54.50% and recovery of 86.26% has been obtained without pretreatment of the high intensity magnetic separation,which are close to the field data.Meanwhile,the iron concentrate with iron grade of 53.96% and recovery of 80.22% has been achieved when the high intensity magnetic separation is used.Though the iron grade and recovery rate have a little descent,this new process can help to significantly reduce processing volume and energy loss.
