Influence of magnetic fields on germanium extraction from ammonia-liquor sludge
The tar liquor from recovery apparatus in coking plants is a secondary source of germanium. Substantial additional amounts can be recovered from the sludge in the collecting mains and coke-oven-gas cooling cycle. This germanium is extracted by scrubbing with ammonia liquor in special mechanical or tower-type mixers, at 80 to 90/sup 0/C. The degree of germanium recovery from the sludge, and the degree of separation between the extract and the sludge, both depend on the partition law. At 80 to 90/sup 0/C, vigorous agitation leads to almost complete mass exchange, i.e., to the establishment of equilibrium between the liquor and the sludge. A laboratory and pilot commercial study has been made of the effects of applying magnetic fields on the degree of germanium extraction from sludge by ammonia liquor.
