iron ore technology processing

In 1879 Sidney Gilchrist Thomas and Percy Gilchrist adapted the Bessemer converter for use with phosphoric pigiron; as a result, the basic Bessemer, or Thomas,processwas widely adopted on the continent of Europe, where high-phosphorusiron oreswere abundant. For about 100 years, the open-hearth and Bessemer-basedprocesseswere jointly responsible for most of the steel that was made, …
