Jul 08, 2021 The aim of this paper is to assess the effect of microwave treatment on copper sulfide ore for ball milling and bed breakage. Liberation analysis of ground products in eight size fractions showed that microwave pretreatment liberated more chalcopyrite particles from the bed breakage product than the ball mill product. In bed breakage, microwave pretreatment caused a 2 increase in chalcopyrite ...
In the original concentrator, material with a copper grade over 0.38 is loaded onto trucks and sent to the milling circuit, where giant rotating crushers reduce the size of the ore to approximately onehalf of an inch. The ore is then sent to the ball mills, which grind it to the consistency of fine powder.
