Copper is one of the oldest forming materials known to man; historians and archaeologists believe that the only metals used before copper were gold and meteoric iron ore. Copper metal has been in use since the aptly named Copper Age. Some of the oldest copper artifacts, such as a pendant from northern Iraq, date to around 9000 BC.
Production. Copper. This long row of large capacity ball mills is used for fine grinding of copper ore at one of the concentrators of the Ut Copper Company. Its mills at Magna and Arthur in Ut are treating vast quantities of the copper so vital for war purposes. [Between 1940 and 1946] Photograph.
Estimated Water Requirements for the Conventional Flotation of Copper Ores . By Donald I. Bleiwas . Introduction . This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
Copper Ore Grinding. Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate.

C. Recycling Copper. In addition to processing copper ores, new and old copper scrap or copper alloys can be melted, repurified, and recycled into new components. It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011).

The Quincy Mining Company Stamp Mills Historic District is a historic stamp mill (used to crush copperbearing rock, separating the copper ore from surrounding rock) located on M26 near Torch Lake, just east of Mason in Osceola Township. It was listed on the National Register of Historic Places in 2007.
Stamp mills are used by miners to crush valuable ore and extract the metals within them. Gold, silver, and copper are common metals that are found within ore, and stamp mills allow these metals to be released from rock for further processing and refining.

Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semiautogenous mills having between 100 and 1,000 ...
Copper in the USA: Bright Future Glorious Past US History. The largescale mining of copper had its origins in the late 1800''s, primarily in the American West. Small mines existed around the country, particularly in the Upper Peninsula of Michigan and in Arizona, but they were able to extract copper only from highgrade ores.
Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper''s flow through the economy are the mining companies, which process vast quantities of lowgrade ore, mostly from openpit mines in order to produce copper. Approximately two tons of overburden must be removed along with each ton of copper ore.

The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semiautogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
