Abstract
The U.S. Bureau of Mines investigated froth flotation techniques to remove heavy metals (pb, cu and zn) from southeast Missouri lead mill tailings. The objectives of the investigations were to reduce the pb remaining in the tailings to <500 ppm and to attempt to recover a marketable concentrate to offset a portion of the remediation costs. Concentrates recovered were retreated to produce a final pb concentrate containing 72 pct pb with a cleaner flotation recovery of 79 pct. Froth flotation proved to be a viable method to remove the heavy metals.
