Mining and concentrating. Silverbearing ores are mined by openpit or underground methods and then are crushed and ground. Since virtually all the ores are sulfides, they are amenable to flotation separation, by which a 30 to 40fold concentration of mineral values is usually achieved. Of the three major types of mineralization, lead ...
