The critical pH for passivation of steel balls during wet grinding of hematite ore was found to be 105 With slurry pH below this critical value corrosion played a significant role in the total wear of steel and the wear was temperature dependent Above this critical value corrosion was prevented and wear of steel mainly due to abrasion was independent of grinding temperature
The viscosity of Pulp will affect the grinding rate directly Elevated temperature the slurry viscosity reduced In order to study the effect on the grinding rate of temperature we did the experiment by only changing the temperature and three groups of contrast test was carried out The results show that the grinding rate is improved obviously when the grinding temperature increases from

Jun 01 2019nbsp018332The dissociation degree of chalcopyrite was good which satisfies the particlesize requirement for flotation However ore that is too finely ground is not conducive to chalcopyrite flotation The grinding cost was high and therefore flotation was more suited to raw ore ground to 5872 0044 mm 33 Flotation
The second stage may proceed at the nitriding temperature employed for the first stage or the temperature may be increased to from 550 to 565176C 1025 to 1050176F however at either temperature the rate of dissociation in the second stage is increased to 65 to 80 preferably 75 to 80
