Beneficiation of an iron ore fines by magnetization

The beneficiation of a hematite ore fines with magnetization roasting and magnetic separation was proposed and studied. • The magnetic properties of ore can be enhanced due to the selective conversion of hematite and siderite into magnetite. • Magnetization roasting can be applied effectively for the processing of carbonate-containing hematite ore.

Beneficiation of a low-grade, hematite-magnetite

2014-5-1  The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization. In this study, process mineralogy and beneficiation of the ore were carried out in the laboratory.

PROCESS FOR BENEFICIATING MAGNETITE IRON

Magnetite (Fe 3 O 4) (molecular weight 231.55 ) contains 72.36 percent iron. Even if all of the iron appeared as magnetite, no more than about 34.5 to 48.4 percent of the ore would consist of magnetite. Since industrial concentration of this ore is accomplished with magnetic separators, only the iron occurring as magnetite can be recovered.

US3672579A Process for beneficiating magnetite

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

Magnetic Separation Principles and Application in

2007-12-1  Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite (magnetic) from

Magnetite: South Australia’s potential

2021-8-3  Magnetite ores require varying degrees of processing and beneficiation to produce an iron ore suitable for steelmaking purposes, ultimately contributing to higher production costs. Magnetite concentrates typically range between 65 to 70% Fe and are increasingly being sought as a preferred feedstock for steelmaking, particularly those concentrates with low impurities.

What Is Iron Ore Beneficiation? (with pictures)

Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
