Steel Raw Materials Methodology Clearly defined and transparent methodologies are the backbone of Plattsâ steel raw materials price assessment processes. Our methodologies provide detailed descriptions of how we assess the iron ore, coking and thermal coal as well as the scrap metal markets.
Scrap metals, in general, are divided into two basic categories: ferrous and nonferrous. Ferrous scrap is metal that contains iron, while nonferrous metals are metals that do not contain iron. Many workers are employed by scrap metal recycling industries. Private, nonferrous recycling industries in the U.S. employed approximately 16,000 employees in 2001.
