Abstract
The article describes the results of experiments conducted for the purpose of determining the effect of the pulp density, the structure, and the operating conditions of the mixing equipment, which cause mass exchange to take place with high intensity, on the rate of oxidation of the sulfide sulfur and the dissolution of uranium minerals when uranium ore is leached in an autoclave whose volume is 0.5 m3. Four types of equipment were tested on pulp having an optimum density. The mixer selected was the one for which the parameters of the process were the best.
When the uranium ore was leached under optimum conditions, after two hours, up to 80% of the sulfide sulfur was oxidized and 70–74% of the uranium was dissolved, which represents very high performance for this type of ore.
A study of the conditions for which there is intensive mass exchange between the phases in the “oxygen-free” autoclave leaching of the ore pulp is of great practical significance, since this factor may limit the rate of the process.
