Chapter 6 Copper Production Technology

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. see figure 6-2 . About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.


Copper Statistics and Information - USGS

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper hode.

Copper Geoscience Australia

Copper is the only naturally occurring metal other than gold that has a distinctive colour. Like gold and silver, copper is an excellent conductor of heat and electricity. It is also very malleable and ductile. Copper is also resistant to corrosion it does not rust very easily . Copper is soft but tough.

occurrence, how it is found, and the means of extraction from its rock enclosure. Iron ore production in Michigan had a humble beginning. Prior to 1840, bog ore found in swamps was used in charcoal furnaces to produce pig iron. This iron ore was of low grade and deposits were small, thus limiting the size and advance of the industry.
