FIELD: metallurgy. ^ SUBSTANCE: group of inventions refers to procedure for extracting gold from coal and to installation for its implementation. The procedure consists in combusting coal and in supplying fumes to a receiver-reactor with liquid in form of acidic flushing absorbing solution. Also fumes are preliminary purified, cooled and compressed to 6 at. Fumes are supplied, while pressure in the receiver-reactor is maintained at 4 at and there is sprayed acidic flushing absorbing solution. Further liquid is run though sorbent. The installation for extracting gold from coal consists of a furnace for coal combustion, of a cyclone, filter, water refrigerator, compressor, and receiver, receiver-reactor with injecting nozzle, branch, tap and safety valve, column with sorbent, reservoir for collection of absorbing flushing solution and a reservoir for drain of gold-free solution. All components of the installation are interconnected by pipes. ^ EFFECT: increased extraction of gold from coal. ^ 2 cl, 1 dwg, 1 ex |
