History of lead mining Minerals and mines Foundations ...

The 19th century was a period which saw Cornish mining technology used to deepen some of the mines in search of richer ore deposits. However, as the lead veins narrow with depth, this proved unsuccessful, and attention was switched to resmelting the lead-rich waste slag and slimes left over from previous medieval mining.

Lead Mining – Concentration process, flotation, filtering ...

Lead is extracted from ores dug from under-ground mines. Even though more than 60 minerals contain lead, only galena, cerussite and anglesite are commercially viable. The U.S. is the world’s largest producer and consumer of refined lead metal. Major mine producers other than the U.S. include Australia, Canada, China, Peru, and Kazakhstan.
