Metallurgical Slag - an overview | ScienceDirect Topics

Metallurgical slags play an important role in the extraction and refining of metals. They are formed when a flux material, added to or included in the charge, reacts with unwanted minerals during extraction or smelting, or with the products of the oxidation of unwanted solute elements during refining.

Metal Profile: Iron Properties and Characteristics

12/1/2020· Characteristics. Pure iron is a silver-colored metal that conducts heat and electricity well. Iron is too reactive to exist alone, so it only occurs naturally in the Earth''s crust as iron ores, such as hematite, magnetite, and siderite. One of iron''s identifying characteristics is that it is strongly magnetic.
