Abstract Novel bulk single-component sulfide catalysts were prepared under the conditions of solid-phase dispersion МoS 2 molybdenite at various mechanical treatment times and amounts polar nonpolar liquid microadditives. The chemical degradation samples in air was found to lead formation surface sulfate anions that shield catalytically active Mo sites. Indirect correlations hydrodesulfurizatio...

Leaching of molybdenite concentrate with hydrogen peroxide in sulfuric acid solution was investigated to determine the effects of reaction time, reaction temperature, H2O2 concentration, H2SO4 concentration, pulp density and rotation speed on molybdenum extraction and molybdenite dissolution kinetics, using the Taguchi method. From analysis of var...
