For example, LIMS separators are installed at the Kiruna plant KA1 in Sweden to process a low phosphorus magnetite ore containing over 60% Fe (Söderman et al., 1996). LIMS is also utilised in Section 2 of the Qidashan mineral processing plant in China ...
Between 2000 and 2010, magnetic separation and flotation were introduced to beneficiate the Sichuan rare earth ore. A combined "gravity-magnetic-flotation" process was developed (Li et al., 2002, Xiong and Chen, 2009), leading to significant increases in rare earth oxide (REO) content and recovery from the Maoniuping rare earth concentrate.
Possibilities For All Flotation Treatment of Titanium Ore. Generally on complex titanium ores it is advisable to use the combination flowsheet shown. An ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product.
ore beneficiation, specific gravity and size-based separations are the most convenient and cost-effective methods [3, 4]. ... of a magnetic separator to lift a particular mineral is dependent not only on the value of the field intensity, but also on the field gradient, which is the rate at which the field intensity increases towards the magnet ...
