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 copper got its name from the word cuprum, which is the latin name of cyprus, the largest site of copper mining during the time of the roman empire. the symbol Cu is also derived from there. until 1982, the US penny was made from 95% copper and zinc. however, now the composition is 97.5% zinc and 2.5%, copper.
