Complex sulphide ore processing with pyrite flotation by nitrogen

Abstract Investigations on the effect of nitrogen on the flotation separation of sulphides from complex ores showed that pyrite floatability was enhanced after nitrogen conditioning. This was used in a novel sphalerite/pyrite separation process demonstrated on a complex ore from New Brunswick (Canada). A possible mechanism of the effect of nitrogen based on galvanic interaction between sulphide minerals is discussed.
