Recovery of tungsten by liquid–liquid extraction from

This work presents the results of the tungsten recovery from a wolframite concentrate (61.5% WO 3) from Igarapé Manteiga (Rondônia — Brazil) after fusion with NaOH followed by leaching with water.The optimum fusion conditions required temperatures above 550 °C to avoid partial manganese leaching. 98.6% of tungsten was leached as Na 2 WO 4 after fusion at 650 °C for 1 h.
