FIELD: non-ferrous metallurgy. SUBSTANCE: autoclave plant has heating autoclaves with drainage pipe-lines and steam elevators, jet heaters positioned on covers of first and second autoclaves connected to each other in succession with siphon-like run-over device with pump, reaction autoclaves with steam elevators connected to each other by pipes, and separator. The last reaction autoclave is also connected by siphon-like run-over device to separator. Upper parts of first and second autoclaves with jet heaters are connected by pipes to drainage pipe-lines of these autoclaves, and upper part of separator is connected to steam elevator of first autoclave and to jet heater.
