Ore is transported to the above ground Coarse Ore Storage Area (COSA) by low-profile 45-ton loaders. Inside the COSA a front-end loader will fill road haul trucks with ore on average 18-24 inches in size. Truckloads are covered before passing through the truck wash and continuing off-site to travel approximately 66 miles to the Humboldt Mill.

Stamp Mills for Processing Gold Silver Copper Ore

A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material releasing the valuable gold from worthless rock allowing for the extraction of gold for further refining. Modern copper smelters use processed copper ore fed into a flash furnace typically fired by oxygen which produces blister copper being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 99.9 purity. Copper can be recycled indefinitely without the base metal being compromised

Mining MillingThe Doe Run Company

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 310 million tons of ore from the Viburnum Trend. Doe Run and our Missouri mining predecessors have mined nearly 510 million tons of ore in Missouri since 1864. Apr 27 2012 · HSS tool bits actually work very well when machining copper. Trick is to have a large swooping radius on the top face of the tool (like this -->) but rotated 90°) and a steep cutting angle of 20° or higher. After grinding hone the cutting edges sharp with an India stone. Works great but needs lubricant as suggested above.
