Appraisal of the Jameson Flotation Cell for Recovery of Cyanide Soluble Copper
Jameson cell pilot plant trials were conducted in a number of areas in the Red Dome gold/copper flotation plant during 1991. The aim of testwork was to reduce the amount of cyanide soluble copper reporting in tailing to the gold leach plant, and hence reduce cyanide consumption. A number of these tests were conducted in parallel with conventional flotation columns. Laboratory tests were conducted to simulate the performance of the existing plant when compared with the addition of the Jameson cell allowing an extra sulphidising phase. This paper reviews the comparison of the Jameson cell and conventional columns in recovering cyanide soluble copper, while maximising copper concentrate grade. Key parameters that are investigated are residence times, air/pulp ratios, superficial gas recoveries and size by size recoveries. A brief comparison of performance of the Jameson cell and column in the controlled potential sulphidisation process is also presented. An estimation of the reduction in cyanide consumption is given.
