Abstract

The extraction of molybdenum into a solution upon roasting the middling is investigated using the mathematical planning method for the experiment. Partial and generalized formulas of the degree of Mo extraction by the Protod’yakonov equation are obtained. This equation is corrected, allowing for a limitation of the degree of reaction (no higher than 100%), by being introduced into the exponent. The value of the activation energy is calculated. It is shown that the limiting stage is diffusion.
