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.
