ancient methods of extracting iron ore

  • How was iron extracted during the ancient times without

    Once purified by various methods usually involving repeated crushing, heating, and washing (crushing divides the mined ore into smaller bits which are more susceptible to various processes, heating burns off some kinds of impurities and makes further crushing easier, and washing separates lighter fractions from the heavier metalbearing ore), the ore would be smelted

  • Ancient iron production Wikipedia

    Natural iron ores are mixtures of iron and unwanted impurities, or gangue In ancient times, these impurities were removed by slagging Slag was removed by liquation, that is, solid gangue was converted into a liquid slag The temperature of the process was high enough for the slag to exist in its liquid form Smelting was conducted in various types of furnaces Examples are the bloomery furnace and the blast furnace The condition in the furnace determines the morphology, chemical composition and the micros

    May 29, 2020  Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers This is also called the "direct process" By the 1100s waterpowered hammers replaced hand hammers for forging out bars of iron

    It is easy to think of steel as iron ore to which carbon is added, but in actual production it was often cast iron from which carbon was removed, a process called " decarburizing," and in China several processes for accomplishing this were used beginning in the Hàn dynasty 汉 (206 BC AD 220)
