Nickel processing - Extraction and refining | Britannica

In carbonyl refining, carbon monoxide is passed through the matte, yielding nickel and iron carbonyls [Ni(CO) 4 and Fe(CO) 5]. Nickel carbonyl is a very toxic and volatile vapour that, after purification, is decomposed on pure nickel pellets to produce nickel shot. Copper, sulfur, and precious metals remain in the residue and are treated ...

Process | Precious Metals Refining

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.

Environmental Guidelines for Nickel Smelting and Refining

Nickel refining Various processes are used to refine nickel matte. Fluid bed roasting and a chlorine-hydrogen reduction will produce high grade nickel oxides (95%+ nickel).
