The contention in the linked article was that atmospheric lead was the result of metal smelting. They're measuring the mining industry as a whole, not lead production.

Whatever they say, they're measuring production of lead and other metals that occur with it. Silver, copper and zinc would be the main ones, I think. Not iron, however.
