The residue fromsilver refiningis treated by affination or parting to concentrate the gold content, which isrefinedby the Wohlwillprocess. From zinc concentrates Zinc concentrates are roasted and then leached with sulfuric acid to dissolve their zinc content, leaving a residue that contains lead,silver, and gold—along with 5 to 10 percent of the zinc content of the concentrates.
