A brief overview on manganese nodules processing
The manganese dioxide and iron oxide phases in nodules are enriched with the valuable metals. However, application of any physical method to separate these phases is practically of no use owing to small size of phases which is about 10–100 Å (Johnson and Glasby, 1969, Murad and Scuhwertmann, 1988). As such, no mineral beneficiation …
