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 bronzean alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are

Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface. Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit
