The Preparation of High-Purity Iron (99.987%) Employing a ...

In this study, high-purity iron with purity of 99.987 wt.% was prepared employing a process of direct reduction–melting separation–slag refining. The iron ore after pelletizing and roasting was reduced by hydrogen to obtain direct reduced iron (DRI). Carbon and sulfur were removed in this step and other impurities such as silicon, manganese, titanium and aluminum were excluded from ...

Smelting - an overview ScienceDirect Topics

Ramesh Singh, in Applied Welding Engineering (Second Edition), 2016. Smelting. Smelting is an energy-intensive process used to refine an ore into usable metal. Most ore deposits contain metals in the reacted or combined form. Magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (αFeO[OH]), limonite (the generic formula for limonite is FeO[OH].nH 2 O), and siderite (FeCO 3) are iron ores, and ...
