As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15% Fe (ironoreformations) and oxidizediron oreof only about 10% Fe (previously mine waste) to 20% Fe (oxidizediron ore…
Get PriceOct 27, 2020·Wolframiteis a weakly magnetic mineral and can be separated by magnetic separation. Wolfram ore coarse concentrate magnetic separation process: before separation, the material is crushed to-3 mm by roll crushers, then they are screened into three levels which are 0.83 ~ 3 mm, 0.2 ~ 0.83 mm and 0 ~ 0.2 mm, and finally you can get wolframite concentrate by magnetic classification beneficiation.
