Process Copper Mining Gold Prospecting

Gold Prospecting, Mining, and Refining Gold Processes ...

Although most gold is produced from alluvial and other surface mining, or from underground reef mining, some gold is produced as a by-product when copper, lead, and uranium ores are refined. An estimated 30 percent of the gold in the U.S. is produced by these means. The exacting process of refining gold.

Prospecting and Mining Gold HowStuffWorks

2009-02-23  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 forms. They know, for example,

Prospecting History - Roadrunner Prospectors' Club

Gold mining became less attractive, and the miners in Arizona turned their attention to copper. From 1900 until the business Collapse of 1929 and 1930, gold mining was subordinate to base metal mining. The only exceptions were the discovery and exploitation of the rich vein deposits of the Gold Road, Tom Reed, United Eastern, and others, in the Oatman district. Gold mining also continued on a ...
