FIELD: metallurgy.
SUBSTANCE: method involves sintering of catalyst, leaching of sinter and deposition of aluminium at the first stage and molybdenum at the second stage from the solution. Catalyst is mixed with soda solution at solid-to-liquid ratio of 1:0.8÷1 prior to sintering. Soda consumption is taken based on 200-400 kg/t of raw material. The obtained sinter is subject to water leaching during 1-2 hours at temperature of 50-80°C. At that, molybdenum is deposited in the form of calcium molybdate at the second stage.
EFFECT: increasing molybdenum extraction efficiency.
