Copper Mineral | Uses and Properties

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.
