Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting pointof 327 °C (621 °F), coupled with its easy castability and softness and malleability, make lead and lead alloysespecially suitable for a wide range of cast products, including

The Betts electrolytic process is an industrial process for purification of lead from bullion. Lead obtained from its ores is impure because lead is a good solvent for many metals. Often these impurities are tolerated, but the Betts electrolytic process is used when high purity lead is required, especially for bismuthfree lead.

The CDC suggests two ways to remove lead from drinking water Reverse Osmosis or Distillation. Reverse osmosis is a simple and economical way to protect your household drinking water by filtering out contaminants like lead. Reverse Osmosis can remove 99.1% of lead in water. Distillation is a very slow process and requires a lot of energy from a
