Particle-based Sb distribution model for Cu–Pb flotation as part of geometallurgical modelling at the polymetallic Rockliden deposit, north-central Sweden

摘要: The polymetallic Cu–Zn ore of the Rockliden massive sulphide deposit in Skellefte District north-central Sweden contains a number deleterious elements relevant concentrations. Of particular concern is amount antimony (Sb) reporting to Cu–Pb concentrate. aim this study was compare different model options simulate distribution Sb minerals laboratory flotation test based on degrees details mineralogical information feed. Experimental data obtained from four composites were used for modelling and simulation. following simulation levels run (sorted least highest level detail their information): chemical assays, unsized bulk mineralogy, sized mineralogy particle information. It shown that recoveries simulated are mostly within error margin acceptable exploration stage deposit. Unexpected high deviation si...
