  Dry Beneficiation of Kyanite Ores | Refractories and Industrial Ceramics

  20131116 · The beneficiation of kyanite ores by a new dry technology is studied. Compared to the flotation method, the method reduces energy consumption from 300 – 400 to 15 – 25 kWh/ton. Dry electroseparation has made it possible to obtain concentrates with an Al2O3 content of 59 – 60% while also producing pure quartz (“tailings”).
