| Abstract: | Mineral processing technology to recover iron from an alkaline maghemite ore from Tibet with low content of sulfur and phosphorus was investigated.A flowsheet consisting of a grinding,a low intensity magnetic separation and a high intensity magnetic separation was introduced to treat this maghemite ore with a TFe grade of 39.23%,and a good beneficiation index of a bulk concentrate yield of 48.86%,a TFe grade of 63.50% and a TFe recovery of 80.50%,can be achieved. |
