Cobalt Beneficiation Technique 911 Metallurgist

2017-11-16  The new cobalt recovery technique is a beneficiation process which uses a combination of fine grinding and froth flotation. The new process enables recovery of about 60 pct of the cobalt that winds up in copper concentrates made from the lead ores. The concentrates are first ground to an average size of 10 µm.

cobalt processing Uses, Supply, & Facts Britannica

2021-7-14  For copper-cobalt ores, a sulfide concentrate is roasted under controlled conditions to transform most of the cobalt sulfide to a soluble sulfate while minimizing the change of copper and iron to their water-soluble states. The product is leached, the resulting solution is treated to remove copper and iron, and the cobalt is finally recovered by electrolysis.

Cobalt Ore Mining Process Equipment Flow Cases

2021-6-23  Cobalt Ore Uses. Cobalt has been used by civilizations for centuries to create beautiful deep blue glass, ceramics, pottery and tiles. In a similar way, it is being used to make paint pigments. In addition to these traditional uses, cobalt is used in a number of industrial applications. When cobalt is alloyed with other metals, very strong magnets are created.

Process for the recovery of cobalt from ores

1997-11-21  A process for the production of cobalt concentrate from an ore containing metal sulfides including sulfides of lead, zinc, and cobalt. The ore is crushed and subjected to a lead and cobalt flotation to separate the lead and cobalt from the zinc and produce a bulk lead cobalt concentrate.

Extraction of Nickel, Cobalt and Iron from Laterite

Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte. High iron (> 35 % Fe)
