Abstract
In order to concentrate of pyrrhotite ore by collectorless flotation in acidic solution, the relation between floatability and formation of elemental sulphur by oxidation of pyrrhotite, galena and sphalerite was investigated. Perfect floatability of pyrrhotite through aeration was obtained by formation of elementary sulphur of pyrrhotite surface in pH values lower than 2.0. Galena and Sphalerite, however, can be floated by using oxidation agent such as H₂O₂in this range. It was confirmed in the batch flotation that collectorless flotation of pyrrhotite with frother and dispersing agent in acid solution was appreciable process to grade up of pyrrhotite ore.
