Mathematical Modeling of Waterless Matte Granulator for Debottlenecking of Conventional Sulfide Smelters

摘要: Within conventional copper and nickel-copper sulfide smelters, ladles of molten matte are fed into converters. These converters blast oxygen-enriched air the matte, thereby eliminating iron sulfur. The converting reactions exothermic and, indeed, converter heat balance is often a limiting consideration on smelter throughput. If portion were in solidified (granulated) form, this would support higher oxygen enrichment, lower volumes offgas, allowing This approach not applied partly because copious amounts water that must be evaporated typical granulators, as Kennecott-Outotec process. current paper recalls waterless granulator had been pioneered 1990’s, applicable to smelters. A mathematical formulation presented can used context simulation-based optimization, estimate size impact granulation.
