GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration ofbase-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.

Extracting Lead Materials fromOre. Lead is a dense, soft, low-melting metal. Lead is the densest common metal except forgold, and this quality makes it effective in sound barriers and as a shield against X-rays.Lead resists corrosion by water, so it makes a long-lasting roofing material.. Only about half of the lead materials used today are produced from mining, the rest is obtained from ...
