Research Abstract

Cobalt-rich ferromanganese crust/nodules are unused resources where the commercial potential will depend on trends in mining and treatment costs of onshore mines. In this study physical separation methods to concentrate valuable components from the substrate rocks were investigated. Liberation ratios of crushed products were measured and separation of fine fraction was carried out using RETAC jig and advanced jig. Treatment flow chart of cobalt-rich ferromanganese crust/nodules was proposed.
