摘要: The current study was carried out to investigate the kinetics of reactions for pressure oxidative leaching a molybdenite concentrate in less than one hour. effects oxygen pressure, stirring speed, pulp density, acid concentration and temperature on rate molybdenum were studied. It found that about 85% oxidized molybdic oxide precipitate with remaining dissolved liquor. Analysis experimental data showed reaction is chemically controlled activation energy 68.8 kJ/mol. Furthermore SEM images no significant boundary diffusion layer it noted precipitates fibrous shape.
