Lead Mining. Lead was a natural resource that became very important to the lives of many Iowans. From the Meskwaki's to the European settlers, lead played a role in Iowa's history. Both groups used the ore to make their lives better. But the story of lead in Iowa's mining history was short-lived. In time the story ended with the decline of lead ...

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.

Of the more than 60 known lead-containing minerals, by far the most important primary ore of the metal is the lead sulfide galena (PbS). Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore.

Question: Zvinakis Mining Company paid $200,000 for the rights to mine lead in southeast Missouri. The cost to drill and erect a mine shaft was $2,400,000, and equipment to process the lead ore before shipment to the smelter was $1,800,000. The mine is expected to yield 2,000,000 tons of ore during the five years it is expected to be operating.
