  • Innovations: Introduction to Copper: Mining & Extraction

    At first, the cosmelting of ores of copper and tin would have been either accidental or the outcome of early experimentation to find out what kinds of rock were capable of being smelted. Significant engineering uses had been found for copper as early as 2750 BC, when it was being used at Abusir in Egypt for piping water.
