Feb 01 1998 This paper describes laboratory and plant based investigations on methods to increase fine copper recovery during flotation treatment of Ok Tedi porphyry sulphide ores. Currently the Ok Tedi concentrator treats a mixed porphyryskarn ore blend which is ground to a d 80 of 180 m with flotation carried out using a dithiophosphate .

Nov 01 2000 Effect of grinding media and Naris on copper recovery 1401 The addition rates of NariS were chosen for their significance in plant processing. The zero addition was selected to determine the effect of eliminating this expensive reagent on copper metallurgy. The addition of 100 gt corresponded to the amount used in laboratory testing at the plant.
Mining SAG Mill Comminution SMC Test. SGSs comminution experts use the SAG Mill Comminution SMC test to characterize ore samples an important first step to grinding circuit design optimization and production forecasting. The SMC test is an abbreviated less expensive version of the JK Drop-weight test. Its key feature is that it is performed on small rocks samples size rocks or drill

Plant survey data showed that recovery of fine copper minerals in the Ok Tedi concentrator was at moderate levels with only 81 of the 10 m copper in the feed recovered in roughing and scavenging stages. Pulp and surface chemical measurements during the survey period suggested that oxidation of copper minerals occurred during processing.
