Abstract

Abstract

A low-grade ilmenite in Panxi region contains TFe 17.14% and TiO₂ 6.32%, which is currently in the undeveloped state. For the equal and efficient exploitation and utilization of Fe and Ti in the ore, research on pre-concentration to remove part of tailings, reduce grinding amount and increase feed grade was conducted. For the sake of reducing cost, pre-concentration experiments with different grain sizes were conducted and the following optimized flowsheet with optimum parameters were obtained. Wet pre-concentration of raw ore with particle size of -3 mm was processed to realize the yield of tailing discharge 29.51%. The concentrate was obtained with Fe grade of 20.74% and TiO₂ grade of 7.97%, Fe and TiO₂ recovery rate of 86.34% and 86.58% respectively.
- low grade ilmenite,
- mineral separation,
