In this process, the sulfide is treated with hydrogen and fed into a volatilization kiln. Here it meets carbon monoxide at about 140F176; (60C176;) to form nickel carbonyl gas. The nickel carbonyl gas decomposes on the surface of pre heated nickel pellets that flow through a heat chamber until they reach the desired size.

From sulfide ores. Because the conversion of nickel sulfide directly to metal would require an extremely high temperature (in excess of 1,600 176;C [2,910 176;F]), the removal of sulfur at this stage of the converting process is controlled in order to produce the 7075 percent nickel matte, which has a lower melting point.
