A comparative study on the effects of dry and wet
Sphalerite showed high flotation efficiency after dry grinding. This can be the result of mechanical activation of the sphalerite surface which enhances the H 2 O 2 concentration on the surface and leads to increased floatability due to stronger oxidizing conditions. Chalcopyrite follows the same procedure as sphalerite and its floatability ...Web
