Abstract
Features of the treatment of non-yielding materials in open and closed systems are considered. The possibility to increase the efficiency of decomposition of difficultly processable ores and concentrates of precious metals in open systems with the use of low-temperature alkaline fusion and acidic oxidative treatment in closed systems - in autoclaves using the microwave radiation is demonstrated.
