Magnetic separator is applied to select materials that particle size is below 3mm like magnetite, pyrrhotite, roasting ore, and ilmenite. The magnetic induction of the cylinder table is 100-600mT. According to customers needs, FTM Machinery can provide magnetic separation of many different surface strengths such as downstream, semi-reverse, and counterflow.

Magnetic separator is a kind of equipment that separates magnetic metals from other impurities according to the magnetic characteristics of the metal materials. It is widely used in resource recycling, timber, mining, ceramic, chemical and other fields, and is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite, and other materials with particle size less than 3mm. In addition, coal magnetic separator is used to de-iron for coal, non-metal ore and building materials. So we can say that magnetic separator is one of the most widely used machines.

Two types of magnetic separators are dry magnetic separator and wet magnetic separator. And the wet magnetic separator is more commonly used. The magnetic separator is used to move all mineral particles in a certain way (the dry selection magnetic separator uses belt while the wet magnetic separator uses a flowing slurry).

You can get the iron ore under the movement of a non-uniform magnetic field, and the separation of ore particles is achieved by the action of magnetic and mechanical force. Different magnetic ore particles move along different trajectories and they will be sorted into two or more separate mineral processing products. The magnetic separator deaign is also unique. It is made of high quality ferrite material or with rare earth permanent magnet material. According to the needs of user, China Fote provides a variety of different forms of strong magnetic separation, such as downstream, semi-reverse, and counterflow.

Dry magnetic separator is energy-saving, efficient and environmental friendly. It can separate lean mine, river sand, and tailings. No water is used in the whole process of mineral processing, and there is no secondary pollution. With it, poor mines become rich, and fine powder grade is improved, a tail throw is lower than the national standard. Fote company specializes in dry selection equipment (dry magnetic separator, river sand dry magnetic separator, permanent magnet iron remover, purification magnetic separator).

Because there is no water in the process of beneficiation, the dry magnetic separator can be widely used in waterless, seasonal water-deficient and cold regions and refractory materials, carbon, coking plants, fly ash, abrasives, coke, steel and steel slag.

The wet magnetic separator is used to separate the magnetic minerals of fine particles or remove the mixed magnetic minerals from non-magnetic minerals. It is usually used in metallurgical, mining or the concentrating plant. The wet magnetic separator has a high magnetic field and is not easy to demagnetize. A magnetic rare earth neodymium NdFeB magnet and ferrite magnet composites the magnetic system.

Many kinds of minerals can be separated by magnetic separator like manganese magnetite, limonite, hematite, siderite, ilmenite, wolframite, manganese ore, manganese carbonate, metallurgical manganese ore, manganese oxide, iron ore mine, kaolin, rare earth ore, etc, so that it is also known as hematite beneficiation plant and iron ore beneficiation plant. The magnetic separator uses the magnetic force and mechanical force affect the ore particle to conduct separation. Ore particle with different magnetism moves in a different track so that two or several products can be separated.

After the slurry is fed into the tank by the feeding tank, the ore is loosely fed into the feeding area under the action of the water. On the influence of the magnetic field, ore particles with magnetism are aggregated to form a magnet or magnetic flux.Subjected to magnetic force in the slurry, they move toward the magnetic pole and are adsorbed onto the cylinder.

Since the polarities of the magnetic poles are alternately arranged in the rotating direction of the cylinder, the iron ore is fixed at work. When the magnet or magnetic flux rotates with the cylinder, magnetic agitation will appear. The non-magnetic minerals such as gangue mingled in the magnet or magnetic flux will be falling off with flipping.

The magnet or magnetic lotus that is finally sucked on the surface of the cylinder is the concentrate. The concentrate passes to the weakest point of the magnetic system with the round barrel and is discharged into the concentrate tank under the action of the flushing water sprayed from the unloading water pipe. If it is a full magnetic roller, we can use the brush roller to unload the ore. Non-magnetic or weakly magnetic minerals are left in the slurry and discharged outside, which is the tailing.

Engenium, a project delivery and engineering consultant to Australias mining sector, was tasked with providing a feasibility study to design new magnetic separation technology. The technology will increase iron-ore production at an existing plant in the Pilbara region of Western Australia. The plan needed to include the type of equipment, concept arrangement, budget development, and schedule delivery. Engeniums two key challenges included delivering the project on a fast track and compressing the feasibility study timeline to reach an investment decision for project execution. The design also needed to focus on layout tie-ins, key equipment, new building footprints and levels, piping routes, and new substation facilities. The layouts would be refined and optimized during detail design. Brownfield tie-ins, new process buildings, and multiple process and layout options were also included in the project scope.

To meet the requirements, Engenium used OpenPlant Modeler and ProSteels 3D plant modeling and digital workflows to develop the feasibility plant designs and pass them on to the owner-operator for review and approval. Engenium also used 3D design models to determine the amount of budget needed to complete the project. The team established a collaborative working environment to determine the process and layout options, while the 3D multidiscipline plant models included tie-ins to the existing plant that produced multiple options to enable value engineering and to support the investment. Engenium also generated critical options analysis and capital estimates using information from the design model. Moreover, identifying the preferred option enabled a fast-track project delivery.

With the project requiring a collaborative design workflow among the multidiscipline design team, implementing an integrated solution using 3D multidiscipline plant models provided significant benefits. Engeniums use of digital workflows enabled the team to deliver the feasibility study in less than two months, saving at least 50% when compared to other projects. Additionally, by using the software, the amount of engineering hours spent on the project were well below the benchmark for an over USD 50 million mining project.

OpenPlant Modeler and ProSteel were used to refine and optimize the layouts at the detailed design stage and, along with Navigator, established new workflows using iModels to implement a collaborative workflow across the multidiscipline design team. Bentley View and Navigator enabled team members to review the design among project stakeholders, allowing them to provide feedback to the modeling team. LumenRT assisted the client with visual presentations of the project to outside stakeholders. iModels were used to make the design file sizes smaller, allowing information sharing across the multidiscipline design team.

characterisation and magnetic concentration of an iron ore tailings - sciencedirect

characterisation and magnetic concentration of an iron ore tailings - sciencedirect

The Quadriltero Ferrfero mineral province is one of the most important sources of iron ore in Brazil. Nowadays this region produces 65% of the Brazilian iron ore. However, since the 1970s, there has been a continuous depletion of high Fe grade ores, obliging the mineral companies to concentrate low Fe grade ores in order to reach the quality demand of the steel mills. It is estimated that 400kg of tailings is produced for each tonne of beneficiated iron ore. This means there is a very big volume of tailings dumped from industrial plants over the years. Owing to the inefficiency of the industrial operations, the tailings deposited in tailings dam have Fe grades similar to or higher than the Fe grades of some iron ores exploited nowadays (3045wt%). Therefore, the reprocessing of this material can recover millions of tonnes of discharged Fe and decrease the volume of the existent tailings, which can be interesting for the environmental and economic sustainability of this region. Herein, we present the characterisation of a tailings sample from a gravity concentration circuit of a mine located in northwest of Quadriltero Ferrfero with the objective of proposing a concentration route for this material. The main characteristics of this tailings sample were: d80=4mm; grades of 30.3wt% Fe and 55.4wt%SiO2, while the identified minerals by XDR, optical microscopy and thermal analyses were quartz, hematite (martitic, lamellar, granular, sinuous, specularitic), goethite (alveolar, amphibolitic, botryoidal), magnetite, kaolinite (5.3wt%) and apatite (0.7wt%). Liberation of quartz for size fraction 0.150mm was of 80%. Bench magnetic concentration of this material increased the Fe grade up to 23wt% and decreased the SiO2 grade up to 39.4wt% in the obtained concentrates, which is satisfactory for the rougher concentration step.

magnetic separation studies for a low grade siliceous iron ore sample - sciencedirect

Investigations were carried out, on a low grade siliceous iron ore sample by magnetic separation, to establish its amenability for physical beneficiation. Mineralogical studies revealed that the sample consists of magnetite, hematite and goethite as major opaque oxide minerals where as silicates as well as carbonates form the gangue minerals in the sample. Processes involving combination of classification, dry magnetic separation and wet magnetic separation were carried out to upgrade the low grade siliceous iron ore sample to make it suitable as a marketable product. The sample was first ground and each closed size sieve fractions were subjected to dry magnetic separation and it was observed that limited upgradation is possible. The ground sample was subjected to different finer sizes and separated by wet low intensity magnetic separator. It was possible to obtain a magnetic concentrate of 67% Fe by recovering 90% of iron values at below 200m size.
