This article experimentally studies the top and bottom styles of CO2-O2 mixed blowing in a pyrometallurgical vanadium-extraction process using a flue gas analyzer and chemical analysis. It also presents the effect of the addition of CaCO3 using a x-ray diffractor, x-ray fluorescence and real-time temperature measurements. The results of flue gas analysis of 15 vol.% CO2 and 85 vol.% O2 mixed blowing...
The prediction of phase configurations and the optimization of operating parameters in the metallurgical process are normally achieved by the multiphase equilibrium calculation (MEC), which is formulated as a constrained optimization problem based on the principle of Gibbs free energy minimization. A revised quantum-behaved particle swarm optimization (RQPSO) algorithm has been proposed to solve the...
The Outokumpu flash smelting process is a very successful technology for copper extraction from sulfide concentrate. Numerical simulation has been used for several decades in the analysis and evaluation of the smelting process. However, significant delay in the particle ignition was found in computations of flash furnaces that had great expansion in their productivity. A study was thereafter carried...
