At furnace temperatures of about 1800 °C, give or take 200 …


These ores are acidic, that is they contain phosphorous, and could only be used after 1879 when Sidney Gilchrist Thomass came up with the idea of adding limestone to the smelting furnace. As about half the iron ore on earth is contaminated with phosphorous this virtually doubled the worlds potentially available steel.
