Feb 12, 2022Single flotation is to first float gold into copper and lead concentrates and then extract gold from these concentrates, so it is an economical and reasonable process for gold ore containing non-ferrous metals in the original ore. Single flotation can not only enrich gold into sulfide minerals as much as possible but also realize comprehensive utilization of polymetallic.
