Vale exploring dry stacking/magnetic separation to eradicate tailings dams. 50,000 t/d per unit, Vale said. In 2011, the company developed a pilot project on the Cianita stack in Vargem Grande, after an investment of BRL100 million. Another solution that has been studied is the dry magnetic concentration of iron ore based on the
The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics. Further magnetic separation and milling produces even higher iron levels in the magnetite concentrate.

Jun 10, 20170183;32;Magnetite ore typically has a lower iron content than hematite ore when mined (~25% to 40% Fe). However, the saleable concentrate product can have between 65 70% Fe content post magnetic separation and beneficiation. Project details. The Iron Bridge Project is divided into two stages focusing on the North Star reserve Stage 1 (North Star
Nagroms magnetic separation capabilities are not limited to WHGMS testing; the company is also host to Davis tubes, pilot and bench scale rapid disc magnets, wet high intensity magnetic separators, an array of wet and dry drum magnets, and more. Hydrometallurgy makes for a large section of Nagroms recent research and development.
Magnetic separation is the process by which magnetically susceptible material is separated from a mixture by the application of a strong magnetic field. Iron ores are usually subjected to the magnetic separation process, due to the high magnetic susceptibility of iron. Magnetic separation was first
Iron ore mines as the main iron source have been widely used in England and Europe. In China, as other mine has much high grade and easy to mining and has a large quantity, though the iron ore mines don not exploited yet, it has great prospects. For iron ore mines mining technology, we have magnetic roasting and gravity separation, but those
Introduction. According to the magnetic difference of various ores or materials, the crude ore or materials realize the final mineral separation under the magnetic force and other mechanical forces.Based on 20 years of mineral processing experience, Xinhai continuously develop and innovate magnetic separation process on the basis of the traditional magnetic separation technology, and has
May 26, 20140183;32;Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is

The magnetic separation feed is wet, meaning that the ore is mixed with water to a ratio of 40% solids. The capacity of the primary unit will be 1,686 tph solids (3,375 tph pulp). The unit will consist of eight 1.2 m x 3.2 m cylinders. The non magnetic tailings will be collected under the separators and will constitute the coarse tailings.

The Lalaua Iron ore mine is an operational iron ore mine in the Nampula Province of Mozambique. The ore is a high grade, and high specific gravity magnetite ore with typically 65%+ Fe content. The specific gravity of the ore ranges from 4.5 to 5.1, making the ore suitable for both the steel market as well as the non steel market.
Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required. The electro magnetic high intensity separators that produce 20,000 gauss, tend to be expensive. However, the rare earth magnetic separators are relatively inexpensive and can produce magnetic fields around 6,000 gauss.
Ore material from the COS is reclaimed by conveyor into a parallel train of two High Pressure Grinding Rolls (HPGRs), which grind the ore to a size of 4 mm or smaller. This ore material from the HPGRs is pumped in a slurry to a stage one magnetic separation. A high magnetic field allows separation of non magnetic material to tailings.
