Aluminum and Silicon Interference During the Carbon Monoxide Reduction of Laterite Ores to Extract Nickel and Cobalt.
NTIS: PB/80-162282 :102 pages
The report describes a study that was performed to better understand products extracted from low-grade domestic laterites using a carbon monoxide reduction and ammonia-ammonia sulfate leach. This understanding was gained through concerted applications of a combination of electron and optical microscopy, electron beam microanalyses, and x-ray techniques that revealed factors influencing low nickel extraction yields from certain laterites and the beneficial effect from the addition of sulfur compounds and halides.
