12.6 Primary Lead Smelting

12.6 Primary Lead Smelting 12.6.1 General15 Lead is found naturally as a sulfide ore containing small amounts of copper, iron, zinc, precious metals, and other trace elements. The lead in this ore, typically after being concentrated at or near the mine (see Section 12.18), is processed into metallurgical lead at 4 facilities in the U. S.

Extraction Of Lead

Feb 20, 2017 Lead mining • Lead metal can be classified as either primary or secondary. Primary lead is produced directly from mined lead ore whereas secondary lead is produced from scrap lead products (such as automobile batteries) which have been recycled. Total annual production is approximately 8 million tonnes, half of which is primary lead.
