cobalt recover from nickel ore

Cobalt extraction Wikipedia

Recovery from laterite ores. Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite

Lateritic nickel ore deposits Wikipedia

Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.

A process is provided for the selective recovery from an impure solution of pure nickel and cobalt solutions, suitable for electrolysis of the respective metals. The impure solution may be that obtained from acid leaching of nickel/cobalt bearing laterite or oxide ore. The impure solution is contacted with a solid ion exchange resin to selectively extract nickel and cobalt, while rejecting at

Cobalt processing | Britannica

In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from solution, usually as a cobaltic hydroxide. But even in nickel smelting, cobalt starts to oxidize before the nickel and can be recovered from the final converter slag. In the ammonia pressure leaching of nickel, cobalt is

Also, SuperLig ® 176 can be used for the combined removal of copper and Fe(III) together with nickel from the cobalt electrowinning electrolyte. For cobalt recovery in a copper sulfide ore process, copper is removed via electrowinning and iron, zinc, and more copper are precipitated by increasing the pH of the solution. Cobalt Winning Operation

Cobalt extraction Wikipedia

Cobalt ore. Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel.
