· The mechanisms by which diesel oil could benefit the flotation of carbon in the Century ore may be related to: • Reduction of MIBC adsorption on carbon. • Enhanced hydrophobicity of carbon. • Better delivery of reagent (through an emulsion). Diesel oil can significantly reduce the amount of MIBC needed (which in the plant is between 400 and 500 g/t; 160 and 200 ppm), and increase carbon ...
