iron increasing the particle size above a specific limit in bacterial leaching studies compared to a mere chemical reaction can have pronounced detrimental effects. A similar series of tests were performed on the same size fraction reducing the pulp density to 2% (w/v). The test demonstrates that decreasing the pulp density from 6% to 2% (w ...An experimental study was conducted to elucidate the evolution of size and chemical composition of La Caridad copper concentrate particles during oxidation under simulated flash smelting conditions. Input variables tested included particle size and oxygen concentration in the process gas. The response variables included the size distributions
