manipulate pyrrhotite performance in flotation is of importance. This can be best achieved if the mineralogical characteristics of the pyrrhotite being processed are known and an understanding exists of how the flotation performance of magnetic and nonmagnetic pyrrhotite types varies. The pyrrhotite mineral group is nonstoichiometric and has the

pyrrhotite processing; pyrrhotite rejection; pyrrhotite tailings inventory Introduction Canada's Sudbury mines have been a major source of nickel for over 120 years. Today, Vale Canada, successor toInco, andGlencore,successortoFalconbridge, remain the major producers in this area. In the 1960s, Inco
pyrrhotite. It can be concluded that the electrochemical activity of steel is much higher than that of pyrite and pyrrhotite. Figure 5 clearly shows that at pH=12 the behaviour of steel is the reverse of that at other pH values, in that the potential increases with time, similar to pyrite and pyrrhotite.
analyses of finely ground chalcopyrite, chalcocite, galena, pyrrhotite, marcasite, and arsenopyrite, to characterize their responses under oxidizing conditions. Thermal gravimetric analysis (TGA) and differ ential thermal analysis (DTA) were used, in the temperature range 1000 to 5000 C.
