Wulfenite dissolves in the presence of sulfide ion according to the following reaction: PbMoO//4 plus S** equals reversible reaction PbS plus MoO** equals //4. Synthetic galena is formed and molybdenum is released to solution as molybdate ion. The reaction follows the shrinking core model and the leaching mechanism involves mixed kinetics where both diffusion and chemical reaction are rate controlling. Molybdenum extraction is explained in terms of temperature, particle size, and sodium sulfide concentration.
