摘要：

Autoclave breakdown of black shale ore without adding oxidizing agent is considered. It is demonstrated by experiment that for total breakdown of ore and vanadium oxidation in an autoclave prior ore treatment is required under atmospheric conditions. IR-spectroscopic analysis shows that under atmospheric conditions CH-groups present in the ore break down and in an autoclave there is breakdown of vanadium minerals. Optimum parameters are established for autoclave leaching of black shale ore of the Balasauskandyk deposit: temperature 140A degrees C, sulfuric acid concentration 150 g/liter, time 2 h. The degree of vanadium leaching is 90%.
