Enrichment of Cobalt Values by Dry Magnetic Separation ...

In order to assess the upgradation potential and possible enrichment of manganese and other valuable traces in general and cobalt in particular, the siliceous manganese ore was subjected to physical beneficiation study. The bulk sample was crushed and subjected to sieve analysis using standard BSS sieves of 500, 250, 150 and 75 µm size.

Enrichment of the manganese to iron ratio of ferruginous ...

The carbothermic reduction of the manganese ore converts the hematite and goethite minerals to magnetite (Fe 3 O 4), with the magnetite then going into the magnetic fraction. The resultant nonmagnetic fraction becomes depleted of iron with an enhanced manganese content.

Enrichment of manganese ore. With the Manganese minerals being significantly heavier than the mainly of silicate consisting waste rock, density separation is a valuable choice in processing the Manganese ore. Since the liberation is adequate in coarse fractions (over 50 mm) of the material, a very high grade can be achieved in the products.

Supergene (geology)

In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.
