Why is lead added to theAmerican Galvanizers Association

Feb 26, 2011 · Hi Harry, All zinc grades contain a small amount of lead, because lead is found in most natural deposits of zinc. Some galvanizers utilize high grade and special high grade zinc ingots which have very low lead content <0.003 or <0.03 and are acceptable for most low lead applications.

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Zinc: smelting, producing and classification Metalpedia

The zinc is scrubbed from the vapour in the condenser via liquid lead. The liquid zinc is separated from the lead in the cooling circuit. Approximately 5,000 metric tons 5,500 short tons of lead are required each year for this process, however this process recovers 25 more lead from the starting ores than other processes.
