A series of experiments was developed to test the flotation response of UG2 ores using the Magotteaux Mill to determine if measurable differences in the pulp chemistry could be discerned using a range of grinding media types. Further, the flotation responses of the contained sulphides (chalcopyrite, pentlandite and pyrrhotite) were determined.

suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind size of this ore should be 92% passing 74 m based on the mineralogical evaluation and the flotation performance. A comparison of a single-stage and a three-stage grinding circuit was conducted.

History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique.

Classic crushers are used for the coarse grinding process. The primary and secondary grinding takes place in autogenous (AG) or semi-autogenous (SAG) mills and in ball or rod mills. If the raw material is sufficiently finely distributed, it is classified in wet-chemical flotation cells according to reusable material and waste rock (residual mineral).
