A beneficiation procedure for possible refractory uses of Bitlis Massif (Turkey) kyanite ore has been developed and involves grinding to d80 = 0˙106 mm, de-sliming, mica flotation, iron oxide flotation and kyanite flotation. A concentrate containing 56˙5% Al2 O3, 39˙01% SiO2, 0˙8% Fe2 O3, 0˙18% TiO2, 0˙09% Na2 O, 0˙1% K2 O and 0˙02% MgO was obtained at a mass recovery of 51˙14% ± 0˙25%. This conforms to both the chemical and size specifications for ceramic uses required to meet American and Chinese standards.
