Title The producing of lead and elemental sulfur by new technologies from galenite ores
Author Boris Krstev, Alexandar Krstev, Dejan Krstev
Abstract These investigations have developed an effective hydrometallurgical method to recover high-purity lead metal and elemental sulfur from simulated galena synthetic mixtures eliminating sulfur gases and lead emissions, in contrast to the current high-temperature smelting technology. The method consists of different operations: oxidative leaching with production of solution with residue containing elemental sulfur, electrowinning by the solution with metal production. The obtained results determined the optimal parameters for possible processing of natural domestic galena ores.
