    From sulfide ores. Because the conversion of nickel sulfide directly to metal would require an extremely high temperature (in excess of 1,600 C [2,910 F]), the removal of sulfur at this stage of the converting process is controlled in order to produce the 70–75 percent nickel matte, which has a lower melting point.
