A process of mineral phase reconstruction (MPR) for modify the mineralogical characteristics of molybdenite was explored.
The MPR product can be leached much faster and more complete than molybdenite under the same conditions.
The leaching kinetics of MPR product with HNO3 in H2SO4 in solutions was studied.
A characteristic “S-shaped” trend occurred, an autocatalytic reaction kinetic equation was proposed.
Based on apparent activation energy and reaction order calculated, the kinetic equation was established.
