Iron ore is converted into various types of iron through several process The most common process is the use of a blast furnace to produce pig iron which is about 92-94 iron and 3-5 carbon with smaller amounts of other elements...
How to Smelt Iron The 6 Steps to Iron Smelting The
Know More
Iron ore can be bought or gathered but for the sake of demonstration we gathered the ore ourselv The best time to collect iron ore is in the winter because the ocean is more active Active waves separate the black magnetic sand from lighter silica sand This magnetic sand is an iron ore called magnetite which when combined with carbon...
Bloomery process metallurgy Britannica
Know More
Bloomery process Process for iron smeltingIn ancient times smelting involved creating a bed of red-hot charcoal in a furnace to which iron ore mixed with more charcoal was added The ore was chemically reduced see oxidation-reduction but because primitive furnaces could not reach the melting temperature of iron the product was a spongy mass of pasty globules of metal intermingled with...
