 — 1. Introduction. Wet milling in ball mills followed by flotation is the general practice employed in the beneficiation of copper sulphide ores in which the major minerals of commercial significance typically are chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS) and chalcocite (Cu 2 S). The flotation response of ground minerals can …

 — Previous studies have investigated the use of balls or rods made from mild steel, ceramic, stainless steel or chrome steel to investigate the effects of different media on flotation. Stainless steel or chrome media have been found to improve the flotation of sulphides compared to mild or forged steel media ( Rey and Formanek, 1960, Peng et al ...

 — The grinding, rougher flotation, regrinding and cleaner flotation procedure was developed based on the pyrite flotation circuit at Telfer. The crushed pyrite (100 g) was combined with 150 g of de-ionized water, and ground in a stainless steel rod mill for 8.3 min using 4 stainless steel rods (3750 g) to achieve a P 80 = 75 μm.

ABSTRACT Copper sulfides mostly occur in minerals such as chalcopyrite, chalcocite, and bornite. Copper extraction requires liberation of these minerals from the host rock by fine grinding, during which rapid oxidation could alter their surface characteristics, thereby affecting their flotation behaviour. The −20 + 10 mm fraction pebbles are compared with …
