Abstract
Missouri lead ores are unique because they represent the only domestic cobalt resource that is presently being mined and processed. Lead, zinc, and copper concentrates are produced from the ore, and since cobalt is detrimental in these products, every effort is made to reject cobalt to the mill tailings. The tailings can contain as much as 45 pct of the cobalt originally present in the lead ore. Researchers at the Bureau of Mines Rolla Research Center used froth flotation to recover up to 65 wt pct of the cobalt and from 60 to 90 wt pct of the other valuable metals such as ag, cu, pb, and zn from the mill tailings. An augmented primary amine collector was used. Desliming of the pulp prior to flotation was not necessary. Improvement ratios range from 7 to 17 depending on the metal.
