Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore. It responds best to what is known as gravity separation as well and several types of gravity equipment can be used to refine it, including jiggers, centrifugal separators, and shaking tables.
Most hematite ore has a very small liberation size that is frequently less than 25μm. Beneficiation of any ore with this fine of a liberation size requires advanced processing methods and is seldom pursued. A single process, known as selective flocculation and dispersion, has been successfully implemented at a plant scale for the beneficiation

Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
1. Magnetite ore stage grinding-magnetic separation process The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage.

Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis
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.
This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30% and recovery of 50.68%
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.

Magnetite concentrate grades are generally in excess of 70% iron by weight and usually are low phosphorus, low aluminium, low titanium and low silica and demand a premium price. Hematite. Due to the high density of hematite relative to associated silicate gangue, hematite beneficiation usually involves a combination of beneficiation techniques.

Hematite is a refractory mineral. Flotation-roasting-magnetic separation process was used in the past. With the development of beneficiation technology, new equipment such as high-intensity magnetic separator, fine screen and gravity separation equipment, reverse flotation equipment and technology are widely used, and hematite beneficiation achieved remarkable results.
In this study, process mineralogy and beneficiation of the ore were carried out in the laboratory. First, mineralogical investigation shows that the main metal minerals are hematite, magnetite and a little octahedrite that cannot be used at present, and the main gangue minerals include albite, quartz and ankerite.
Mineral beneficiation technology is facing the biggest challenge of finding out innovative, efficient and cost-effective solutions to the complex problems associated with processing of difficult to treat low grade iron ores. The changing trends of the industries have evolved several changes in the processing technology in the recent past.
Beneficiation of Magnetite–Hematite Ores. Studies have found that the ore contains both strongly magnetic and weakly magnetic iron minerals. To enrich the strongly magnetic component of the samples (magnetite), the field induction in the mineral separation zone must be in the range of 0.1–0.2 T.

Studies to evaluate the beneficiation of low-grade hematite-magnetite ore (18.64% Fe) have been carried out in China (Liu et al., 2014). Bioprocessing has been considered as an option in the
Mineral processing methods are mainly divided into two categories, namely physical mineral processing and chemical mineral processing. Physical Mineral Processing Physical beneficiation includes magnetic separation, gravity separation, electrostatic beneficiation, friction beneficiation, particle size beneficiation, shape beneficiation, corona beneficiation and manual beneficiation.
Introduction: Ore, which contains an economical use of iron, is called an iron ore. There are many types of iron ore, magnetite (Fe3O4), hematite (Fe2O3) and (FeCO3), etc, which are mainly used
Hematite and goethite are very friable during mining and processing due to inter-granular pore spaces and voids along the weaker bedding planes. These friable particles break down and account for the iron content of the slime. Ore samples, having magnetite and martite do not participate in the formation of the slime as they are very massive .
The crushing system of hematite ore uses Three sections + One closed circuit process generally. After hematite ore crushed, its basic beneficiation process is Periodicity grinding or continuous grinding—weak Magnetic Separator—high gradient strong Magnetic Separator—anion reverse Flotation process. According to the difference of

Answer (1 of 2): According to the types of iron-containing content, the common iron ore can be divided into magnetite, hematite, martite, v vanadium titano-magnetite, limonite and siderite ore and mixed iron ore that consists of two or more than two iron-containing content.
Hematite separation process is suitable for complex structure hematite such as hematite and impurities with uneven distribution of particle size, ore with large content of fine particle, ore with small amount of magnetite and the gangue minerals containing quartz or kaolin.The beneficiation process includes stage grinding, coarse-fine particle separation, heavy
This magnetite beneficiation process has the advantages of a simple reagent system, low flotation temperature, suitable for field application, easy to operate, and strong adaptability to the change of process flow. Low intensity magnetic separation-anionic reverse flotation process
Among them, magnetite-hematite is a common mixed ore, and its beneficiation usually adopts a combined process flow composed of multiple beneficiation methods. Single Magnetite-Hematite The single magnet-hematite is mostly fine-grained; the gangue mineral is mainly quartz, and some of it contains iron silicate.
