How is cobalt mined?
Cobalt likes arsenic, and the arsenide is mined to recover cobalt only in Canada and Morocco. There are a number of other locations where cobalt is recovered as a byproduct of copper or nickel production. The metal is not rare, and there are over a dozen countries where cobalt is produced. Open pit mining is the method of the recovery of ore from the ground. In the locations where the mining is done, ore is blased loose, then scooped up, loaded and transported to a mill. There it is crushed and processed. This true whether cobalt arsenide is being recovered or whether copper or nickel are being recovered. Need links? You got 'em.
