Vale has inaugurated its new dry pilot plant for processing iron ore in Minas Gerais, Brazil, as it continues to reduce its use of water in ore and waste processing. The Brazilian technology, known as FDMS (Fines Dry Magnetic Separation), is unique and has been developed by New Steel – a company Vale acquired in late 2018 .
Description: Iron ore fines come from the natural raw iron ore through the process of mining, crushing and screening, where the iron ore is separated into lumps and fines. Iron ore is done in this fashion so that it can be used for the iron/steel making industry. When the iron content in the processed iron ore contains more than 60%, which ...

screens have been used in iron ore since the 1950's processing all types of iron ore. From removing fine impurities in Direct Shipping Ore sinter products to scalping relatively coarse (+53 to 75 µm) middlings and size control in pellet concentrates.
Sintering is a process of Agglomerating iron ore fines into a porous mass by incipient fusion caused by combustion within the mass of the ore particles. History of Sintering: Iron ore fines (0-10 mm) which were a result of mechanized mining could not be charged in a Blast furnace because they reduce the permeability of burden in a blast furnace.
The proposed dry, stable and self-fluxing tailings concept follows the same steps as the front end of the wet screening procedure. First the tailings product would be deslimed at 325 mesh (45 microns). The coarse fraction would be vacuum filtered. The slimes or fines fraction would employ a two-step solid/liquid separation to produce a wet cake ...

"The contracting of a dry screening plant for processing the top layer of the Riley deposit affords the company the opportunity to accelerate production and capture the current iron ore prices before the wet screening plant has been built and commissioned, and also reduce the capital cost requirements," it added.
Deep dry screening is the key unit in mineral processing. A vibrating flip-flow screen (VFFS) can provide effective solutions for screening fine-grained minerals, and it has been extensively used in many industrial fields. An accurate dynamic model of VFFS considering the influence of materials is significant for its dynamic analysis and screening process research, but it has rarely been ...
Dry processing at Vale. In the last 10 years, Vale invested almost R$66 billion in facilities and development of technologies for the dry iron ore processing production. Today, most of our iron ore production (about 60%) is through dry processing. The natural moisture processing is used at Carajás and Serra Leste mines, at S11D Eliezer Batista ...
Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help ...
Characterization and beneficiation of dry iron ore processing plant reject fines of Khondbond region, India, was investigated. Different characterization techniques viz. size analysis, size-wise chemical and density analysis, X-ray diffraction analysis, sink-float analysis, thermo gravimetric analysis, scanning electron microscopy, and QEMSCAN were carried out.
This approximation of fines is used to give an idea of the results to be expected after screening. That is, it will be used to determine the efficiency of the screening process. The entire mass of the ore is then fed onto the industrial screen. The ore is fed manually onto the screen at a feed rate of 3.03 t/h i.e. 11.965 kg in 14.2 seconds.
If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter the equipment line.

Both fines and ultra-fines are disposed in a tailings dam inside the mine operation area. Thickening, filtering, and dewatering screening tests were performed to demonstrate the feasibility of tailings dry stockpiling and eliminate the need of a tailings dam. 2.1. Thickening tests. Thickening tests were performed using laboratory scale thickeners.
Leading iron ore producers are already implementing SuperStack screening technology in innovative applications. Vale S.A., one of the world's largest iron ore is installing SuperStacks for fine iron recovery at the Carajás mining complex to transform their tailings into positive cash flow with a by making a high-value "green ore" product from what was previously considered waste.
The iron ore in this area contains a large volume of fines (20–30% below 150 μm), which can be transformed by high moisture content into a sticky mass that is almost impossible to screen. Vale initially considered wet-process screening using water sprays to overcome the problem but ultimately rejected that approach as too costly.
Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.
