THE RESEARCH ON MINERAL PROCESSING TECHNOLOGY OF INDIA IRON ORE

Zheng Gui-bing

Abstract

Mineral processing technologies have been studied for a iron ore in India,the iron concentrate is obtained with grade of 64.23%and recovery of 74.89%by flowsheet of stage grinding-coarse fraction and fine fraction magnetic separation respectively,the iron concentrate grade is 64.57%with recovery of 72.11% by magnetic separation-reverse flotation flowsheet,the iron concentrate grade is 67.98%with recovery of 95.18%by roasting-magnetic separation flowsheet.At present,the optimal technology is stage grinding-coarse fraction and fine fraction magnetic separation respectively.
