  • Basic Principles of Metallurgy and Metalworking

    metallurgy involved the pure metal, iron, which is the most abundant in the earth's surface but which is far more difficult to work than copper or tin. Iron had a melting point which was too high for primitive furnaces to extract in pure form from its ore (image shows a banded iron formation). 14 Basic Principles of Metallurgy and MetalworkingWhat is Metallurgy ? Metallurgy for Dummies,The Iron Age began around 1,200 BC when the Hittites discovered how to extract iron from ore and work it to advance their cultural aims. Georg Agricola, considered to be the father of metallurgy, detailed ore mining and metal extraction procedures, as well as other aspects of the science, in his 16th century book, De re metallica.

  • Ancient Metallurgy University of California, San Diego

    Metallurgy is the process of working metal into artifacts (tools and toys). Although small amounts of metals are found in relatively pure form, most must be extracted from more complex ores by removing the "impurities" (non-metal or other metal) from the combination ore.Iron Mining and Metallurgy Encyclopedia,IRON MINING AND METALLURGY. Iron mining, refining, and manufacturing were at the core of early American industrial development.
