Controlled Potential Sulphidisation (CPS) - Demand for a lab-scale process flow-sheet (1 reply)
Please join and login to participate and leave a comment.
Hello
recently, I am working on processing of a gold bearing mixed oxide-sulfide copper ore (Av. Cu; 0.80 & Av. Au; 0.2ppm).
After some research and testing different methods, I found Controlled Potential Sulphidisation (CPS) Flotation as the most effective & practical method on similar ores (E.g., Kanmantoo, Australia & Kansanshi, Zambia).
I am working in a processing lab, which is fully equipped for sulfide ore flotation tests, but I have not done a real CPS test yet. Until now, sulphidisation have been done there by simple adding specified amount (g/t) of Na2S.
Recently I bought a Silver/Sulfide Ion Selective (combination) Electrode (IONODE), for controlling Es in during sulphidisation (-600mv) and flotation (-450mv) stages. But I still have many question and difficulty in using this electrode and caring out a standard CPS Flotation test.
I need someone to guide me to conduct a standard CPS test.
I also need a detailed standard flow-sheet of CPS lab-scale test, or a sample lab report, if possible.
Any assistant/advise/answer/file would be greatly appreciated...
