History of Lead Mining in Missouri DNR

Estimates of the aggregate lead production in Missouri since mining began in the early 18th Century, top 17 million tons, at a value of nearly 5 billion dollars. Today, Missouri has the largest active primary lead smelter in the United States (Herculaneum) and the largest secondary lead smelter in the world (Buick).

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 leadrich waste slag and slimes left over from previous medieval mining.
