Jordan Ancient Metallurgy of Social Sciences
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 several processes for accomplishing this were used beginning in the Han dynasty 206 BC AD 220
Iron Ore Fact Sheets Mines Atlas
Iron ores are rocks from which metallic iron can be economically extracted These rocks are usually found in the form of hematite Fe2O3 or magnetite Fe3O4 About 98% of world iron ore production is used to make iron in the form of steel Iron ore provides the foundation for one of Australia s major export industries
Innovations Introduction to Copper Mining Extraction
The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals Such ores originate from sulfur bearing volcanic magmas which have separated into metal sulfides and
