摘要
In the light of the knowledge gained by the study of electrochemical flotation for galena and selective flotation of galena from lead zinc iron sulfide ores, a technology for accurate potential control based on intrinsic electrochemical behavior in grinding flotation systems has been developed and is called "Original Potential Flotation (OPF)". The optimum conditions for the original potential flotation of galena from Pb Zn Fe sulfide ores are as follows: pH values of 12.5 12.8, potential of 150 180 mV and with diethyldithioncarbamate (DDTC) as collector. Lime is used as a regulator of pH, meanwhile, and can stabilize special potential very well, and this special potential is exactly the flotation potential of galena. This technology has been applied successfully in potential control flotation of galena in many complex lead zinc iron sulfide mines in China.
