Slags from smelting of copper still contains up to 20 % of copper inclusions, which can to some extend be recovered by a special cleaning process. The long-term goal of the authors is to use numerical MHD to simulate the complex slag cleaning process in detail and to optimize it. The paper presents preliminary results on simplified test cases and configurations.
It turned out when simulating the copper droplets in the slag by a discrete phase model, the pure stochastic parcel collision algorithm in FLUENT failed to provide mesh-independent and precise results for inter-droplets collisions and coalescence. Therefore, a new hybrid collision algorithm and the updated coalescence regimes were implemented in FLUENT. Several benchmark tests were reported in order to demonstrate the significant differences between the two algorithms and the main advantages of the new hybrid algorithm for simulations on the slag cleaning process.
