Abstract
Cobalt is not generally found alone in commercial deposits but mostly occurs as a small but valuable constituent in most nickel and a few copper ores . Its concentration and extraction are therefore intimately linked to the recovery of the primary metals and the major task for the metallurgist is to extract cobalt of commercial grade from a much larger mass of either nickel or copper and sometimes both. This paper provides an overview of the mineralogy of the main deposits being currently exploited that contain cobalt as a by product. The concentration and then extraction to metal are reviewed and some advances released into the public domain are discussed.
