Iron ore sintering with charcoal: Mineral Processing and ...

2013-7-18  The iron blast furnace is the most widely used and efficient producer of liquid iron; however, emissions from sintering and coking cause environmental pressure for the integrated steel works. The combustion of coke fines (breeze) during sintering contributes to greenhouse gases (e.g. carbon dioxide) and is a source of SO x and NO x emissions ...

A Comparative Study on Characterisation and Processing

2012-12-19  INTRODUCTION Indian iron ores are generally quite soft and friable in nature and generate significant amount of fines while mining, processing and handling. Also on crushing and sizing of ores, the high alumina bearing laterite and friable ores have greater propensity to break down into fine sizes as compared to hard ores.

2021-8-13  Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.
