Open-pit copper mining, smelting, and production | Britannica
In the final extraction step—refining—any remaining minor impurities are removed from the anodes. The result is almost 100 percent pure copper. This metal will be sent to other plants to be made into products such as copper pipe and copper wire. Most of the world's production of copper is …

Copper in the USA: Production of Copper
The copper industry in the United States has two main segments: producers-mining, smelting, refining companies; and fabricators-wire mills, brass mills, foundries, powder plants. The end products of the producers, the most important of which are refined cathode copper and wire rod, are sold almost entirely to the copper fabricators.

Copper Refining: Explained Step-by-Step
In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.In these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.

Prospecting and Mining Gold | HowStuffWorks
The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise. First, geologists know more about how gold ...
