Abstract
Research to find basic technology for CO and ni recovery is part of an overall effort by the Bureau of Mines to help reduce import vulnerability by enhancing the nation's ability to produce critical and strategic minerals from domestic resources. The Missouri lead ores mined annually contain sufficient CO to provide about 25 pct of current national demand, if all of it could be recovered. About 5 pct of that CO reports to the pb-smelter mattes, along with quantities of as, ni, pb, ag, and cu. Not only is this a loss of CO, but it makes the matte unsuitable for environmentally acceptable cu recovery techniques. This paper describes the basis for selective oxidative (mNO2-h2so4) leaching of the matte, followed by selective recovery of salable or usable products of cu, CO, ni, and mn from the resulting leach liquor.
