Modelling and simulation of a copper slag cleaning process improved by electromagnetic stirring

Abstract

Electromagnetic stirring in a copper slag cleaning process aims at improving the recovery efficiency of the finely dispersed metallic materials from the waste. In the present study the multiphase problems involved in the slag cleaning process are numerically investigated. An Euler-Lagrange approach with advanced collision and coalescence modelling is employed. The corresponding methodologies are briefly introduced and discussed. Based on the implemented sub-models, the copper recovery is numerically investigated for operating parameters corresponding to industrial pilot plants.
