## Mond process for refining nickel

Get Price

The Mond process is the refining process for Nickel metal from its mixed state. It is also regarded as carbonyl process as the Metal is bound to Carbon monoxide first and then heated to remove all the impurities associated with the Nickel metal. This process was developed by Ludwig Mond in 1890, the era of metallurgical processes
