Abstract

Results of modeling of changes in technological properties of sulfide minerals (pyrrhotite, pentlandite, and chalcopyrite) present in mining-industrial wastes stored in a climate in which evaporation prevails over precipitation are reported. It is proved that flotation activity of chalcopyrite and, in particular, of pentlandite diminishes, pyrrhotite increases, and selectivity and flotation of combined sulfides with respect to other minerals increases insignificantly. The content of water-soluble salts, dominated by nickel sulfates, increases with storage time.
