The copper oxide melted chemically in the slab is reduced and recovered. The gold and silver in the melted gold- and silver-contg. silica ore are absorbed into the settled and separated copper-component, by which the gold and silver are recovered. The temp. is preferably maintained at about 1,200-1,300 deg.C in order to melt thoroughly the above-mentioned silica ore. The gold and silver in the gold- and silver-contg. silica ore are thereby recovered at a good yield and the slag cleaning of the copper converter slag is executed.
