  • 3.2.7 Extraction of Metals - Principles of metal extraction

    Metals were neither easy to be found out, nor it was easy to make tools out of them Because, though some pieces of free copper or meteoric iron was available in nature, most of the metals were embedded in ores, which were difficult to use unless mining and smelting were learnt. In fact, there were four major stages in metalworking:
