Iron processing - Ores Britannica

As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.

Numerical Modeling of the Iron Ore Sintering Process

The iron ore sintering process is extremely complicated, involving a large number of inter-related vari-ables. Since the 1950s many studies have been carried out to understand the factors that determine sinter plant perfor- mance – usually expressed in terms of productivity, coke requirements and product quality – and the effect of raw material properties (viz., iron ore, flux and adjunct ...

Mining of Iron Ores – IspatGuru

14/03/2014  The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.

The Six Main Steps of Iron Ore Processing Multotec Canada

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency. Fine particles make the crusher less efficient and increase the power draft ...
