Cobalt Mining Legacy

Once ore is extracted from a mine it is processed to recover the valuable minerals. Ore is normally a mixture of a small amount of valuable minerals with much larger amounts of waste minerals of no value (gangue). Some ore at Cobalt was an exception to this – so rich that there was more silver than gangue.

Exploring Cobalt The Historic Silver Capital

Although most of the known ore was mined out, mining was carried out at intervals by various interests from 1937 to 1982. From 1905 to 1943 the deposit yielded close to 1 057 502 000 g of silver, some 8493 kg of cobalt, a small amount of copper nickel, making it one of the most productive mines in the Cobalt

How Hydrometallurgy and the SX/EW Process Made

In addition, the process can be used to extract copper in situ. That is, without removing the material from the waste pile or from the ground. The net result of the use of this process is that copper can be produced from sources that in the past would have gone untouched, thus reducing the reliance on conventional ore bodies.

Enhanced methods for nickel recovery

The method of PAL involves preheating the slurried ore, and leaching with concentrated sulfuric acid at high temperature and pressure. Nickel and cobalt are converted to soluble sulfate salts, and are recovered from the slurry in a counter-current decantation circuit (CCD).
