Simulation and experimental verification the treatment of dispersed zinc and iron bearing materials using software package for the Waelz process (SPW)

Abstract

Simulation of the Waelz process, using Software Package for the Waelz process (SPW) was studied. SPW is a mathematical model used for calculation the technological parameters of processing zinc bearing materials in the Waelz process. The used materials was zinc oxide – PbAg residue (Concentrate A) and zinc neutral leach residue (Concentrate B). Experiments have been performed in order to verify the results obtained by simulation. Results of experiments were in correlation with the results from simulation. Distribution of zinc from input charge to clinker in simulation and experiment was 5.94% and 9.46% respectively.
