After leaching the nickel out of the nickel speiss and turning it into nickel sulfate, the remaining precious metals residue is treated at the precious metals refinery. The copper matte is returned to the smelter. The depleted blast furnace slag is physically calibrated for use in the concrete industry or used as dyke fortification substance.

Using nickel flash smelting technology it is possible to process sulfide nickel concentrate and produce nickel matte and slag in a relatively efficient process. Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte.

The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most wellknown purification processes is called the Mond Process,...
