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.

Gold cyanidation technology is a technology process which put activated carbon into pulp and leaching with absorbing gold at the same time. It includes the stages such as leaching pulp preparation, leaching and adsorbing, gold removal carbon recycling, pulp agitation, and gold loaded carbon desorption.
Jun 11, 2020 The copper flotation plant in Pakistan has a processing capacity of 1500tpd. The raw ore was characterized by simple composition. It consisted of metallic minerals (copper pyrite and pyrite) and non-metallic minerals (quartz and chlorite). The multi-element analysis results showed that Cu was the valuable element.
