Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material.

magnetite is the principal iron mineral, the rock is called magnetic taconite; if hematite is the principal iron mineral, the rock is called hematic taconite. About 98 percent of the demand for taconite comes from the iron and steel industry.

This work involves the analysis of collected ore samples from Anka in Zamfara State. The samples assaying % of Cr 2 O 3 was subjected to beneficiation process in order to enrich the ore, in terms of the Cr 2 O 3, using magnetic separation.
Iron ore is common in many mineral forms (hematite, magnetite, goethite, limonite or siderite) and has mineralspecific analysis requirements. Borate fusion with XRF analysis is an extremely robust technique for major and minor elemental analysis in complex mineralization and offers highly precise and accurate results for iron ore samples.
Strong magnetic iron ore separation process It is used to low grade magnetite. Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding.

Slag formation in the gratekiln process is a major problem for ironore pellet producers. It is therefore important to understand the slag formation mechanism in the gratekiln production plant. This study initiated the investigation by in situ sampling and identifying particles in the flue gas from a fullscale 40 MW gratekiln production plant for ironore pelletizing.
