Production of cobalt metal
To by alloys of cobalt from the supplier KMZ can at an affordable price. The price is formed based on the European standards of production. The provider offers any rare earth metals at an affordable price wholesale or retail. Supplier KMZ offers any rare earth alloys under the order.
On world market for the production of cobalt have been significant changes At the end of XX century, the production of this metal has moved from Africa to Europe, and today in China. Without a doubt, the most important event that occurred on the world market in recent years has been the rapid growth of the mining industry of China. Today, China produces twenty-three percent of the world cobalt rental.
Them rich deposits of this metal are almost exhausted today. The source of cobalt-containing raw material is Nickel ores which require beneficiation to obtain a concentrate. The concentrate is treated with a solution of sulfuric acid, or ammonia, or methods receive the pyrometallurgy of sulfide or metal alloy. This alloy is then subjected to leaching.
The most difficult to separate cobalt from close to it in chemical properties of Nickel. The solution containing the cations of these two metals is treated with strong oxidizing agents chlorine or sodium hypochlorite. Black precipitate Co (OH)3 is calcined to remove water, and the resulting oxide From the3 On4 are reduced by hydrogen or carbon.
