Characterization of Slags Produced During Gold Melting

2015 1 1   Experimental procedure 2.1. Melting process First, 3 slag samples are obtained by melting mineral concentrates, using PbO 2 as a flux in the melting process. Melting is carried out in a Lindberg furnace at 1000Â C during 1 h. The PbO 2 is reduced to a metallic Pb, which collects the precious metal.
