Oxidative Sulfuric Acid Leaching of Lead Smelter Mattes.

PB80111669

Publication Date	1979
Personal Author	Sandberg, R. G.; Hebble, T. L.; Paulson, D. L.
Page Count	26
Abstract	The Bureau of Mines, U.S. Department of the Interior, is investigating a hydrometallurgical procedure to conserve cobalt, nickel, and copper by recovering the metals from the matte byproducts of smelting Missouri lead ores. For want of adequate processing technology, the mattes are now either unmarketable or marginally so. The procedure involves leaching with manganese dioxide and sulfuric acid to obtain copper, nickel, cobalt, lead, and manganese sulfates, and elemental sulfur. The soluble metals are recovered from the leach solutions by caustic and sulfide precipitation, and the residue returned to the smelter for lead recovery. The manganese can be reclaimed from the spent leach liquor as manganese oxide and recycled to leaching.
