摘　　要：本文从黄铁矿类硫化矿物和碳酸盐类矿物在浸出过程中的化学行为出发,通过正交试验结果分析,阐述了含硫碳酸盐型复杂铀矿石加压氧化处理的可能性。复杂铀矿石经加压氧化处理后,浸出试剂用量减少,铀浸出率升高。In this paper the possibility of pressure oxidation processing for the sulphide-bearing carbonate type complex uranium ore is expounded proceeding from the chemical behaviours of pyrite sulphide and carbonate minerals in leaching process and through analysis of orthogonal array test results. The consumption of leaching reagent was decreased and the extraction rate of uranium was increased after pressure oxidation treatment of the complex uranium ore.
