lead mining process

Mining Milling

We produce lead, copper and zinc concentrates to sell around the globe. Production in this area began in 1960. Since that time, we have mined nearly 315 million tons of ore from the Viburnum Trend. Doe Run and our Missouri mining predecessors have mined nearly 515 million tons of ore in Missouri since 1864.
