· flotation is a selective process and can be used to achieve separation from complex ores such as leadzinc, copper zinc developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expanded to include oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and .
In the case of lowgrade mines or where the product iron grade needs further improvement, the secondary crushing is replaced by a beneficiation process. As shown in Fig. 1, the beneficiation process mainly comprises the subprocesses of grinding, separating and dewatering. Grinding Grinding is a subprocess of finely grinding ore
The process development for the upgradation of Sangan lowgrade iron ore by DLIMS was performed and a flowsheet was proposed. The results showed that after two steps of DLIMS it is possible to produce a concentrate with iron grade more than 50% which can be sold as highgrade iron ore or fed to the onsite processing plants. Keywords Sangan mine
