摘要
An improved method of processing both primary and secondary nonferrous metal and alloys of said metals using a refining gas having a global warming potential is provided. The improvement involves reducing said global warming potential of said refining gas by refining said non-ferrous metal and alloys with a gaseous mixture including at least one compound selected from the group consisting of CIF3, CIF, COF2, F3COF, CF2(OF)2, SO2F2, NF3, SO2CIF, SOF2, SOF4, NOF, F2 and SF4.
