A novel mathematical model for combustion of a single copper concentrate particle is presented. The model includes particle volatilization, fragmentation, smelting, and combustion phenomena. This model has been incorporated into a general computational fluid dynamics code to calculate flow field and particle trajectories needed to simulate the smelting process in flash furnaces.
furnace for smelting concentrate and producing copper matte. The reverbs began to decline in the The reverbs began to decline in the 1970s with the adoption of environmentally and energetically superior processes like flash smelting.
The thermal decomposition of the copper concentrates was determined by differential thermal analysis and thermogravimetry (DTA TG). The information was correlated with the chemical composition and the mineralogical phases of the samples identified by Xray diffraction.
