United States annual primary production of zinc from mines and smelter. Zinc mining in the United States produced 780,000 tonnes (860,000 short tons) of zinc in 2019, making it the world's fourthlargest zinc producer, after China, Australia, and Peru. Most US zinc came from the Red Dog mine in Alaska. The industry employed about 2,500 in mining and milling, and 250 in smelting.

Using cyanide to separate gold was, as mining historian Jay Fell writes, "far more efficient than stamp milling and far less expensive than smelting." Like earlier stamp milling, the process involved crushing the gold ore into sand, but instead of running it over copper plates or through sluices, the cyanide mills sent the sand into vats of ...

hese steps were mining, milling, and smelting. Mining was taking the rock with copper in it out of the earth. This was the first step. The second step was separating the copper from the rock. This is milling. The last step was smelting, which was melting pieces of copper mineral together to make concentrated metal.
