Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

BALL MILL GRINDING Grinding the washed rod mill discharge to approximately 90% minus 200 mesh was necessary to get fairly good liberation of the copper and zinc from the bulk of the pyrite Lime was added to the ball mill to give a pH of about 10 for depression of the pyrite

Cu

Abstract: Cu-Zn alloy was prepared by high energy ball milling of elemental copper and zinc by the Simoloyer attrition mill the different parameters such as milling time ball-to-powder ratio and rotational speeds were analyzed The results show that the different Cu-Zn alloy phase can be produced by different ball milling parameters It has been found that milling time is highly significant
