After washing with water and drying, the gold could be melted and cast into bars. Although the process captured 90 percent of the gold, mills quickly abandoned the process because of the expensive reagents, inefficient and clumsy process and deadly chlorine gas. German scientists discovered cyanide's ability to dissolve gold in 1846.
Article By Gary Carter. Photos sourced by Western Mining History. Numerous articles and books have described the techniques to extract valuable metals from waste rock.
