Aug 01, 2016· The influence of the addition of Cu 2+ during grinding with the forged steel and high chrome white iron grinding media on the floatability of a single pure pyrite is shown in Fig. 3. As seen in Fig. 3, the floatability of a single pure pyrite when grinding was performed with the forged steel media was almost three times higher than that with ...

the main properties of grinding process

in minerallurgy, grinding is usually a preparatory process for the ore concentration and/or hydrometallurgical processing. There is a decrease in the size of the ore and a release of particles, opening the splices of valuable minerals to each other and related minerals. After grinding, the ore leaves with dmax = 0.1-0.01 mm.
