Iron Control in Zinc Pressure Leach Processes

IntroductionProcess ChemistryIntegrating Zinc Pressure Leaching with Roast-Leach OperationsDynatec's Two-Stage Zinc Pressure Leach ProcessesCountercurrent Two-Stage Pressure LeachingCocurrent Two-Stage Pressure LeachingFluoride DeportmentConclusionsConventional zinc concentrates typically contain 5-10 percent iron. The iron commonly associated with zinc concentrates can be present as either a replacement for zinc in sphalerite or marmatite or as separate minerals, such as pyrite, pyrrhotite, or chalcopyrite. Consequently, the disposal of iron residues is an integral part of the design and operation of zinc refineries. Zinc has been recovered from sulfide concentrates by hydrometallurgical routes for almost a century. The disposal of iron was a major difficu…

Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting.
