Wills et al., 198710, investigated the thermally assisted liberation of cassiterite in an ore mined at South Crofty. Previous work on this ore (Sherring, 1981)14 had shown a 55% reduction in grinding resistance when the ore was heated to 650C and then rapidly cooled, however, this was greatly offset by the energy required to heat the material.
