·The magnetite ore which makes up a large percentage of the existing orebody is mined as part of the usual open cut mining process Processing Copper and gold are recovered from the ore using traditional grinding and flotation methods in the concentrator Magnetite is liberated during this process and the magnetite
·The final stage in iron ore processing is ironmaking where the iron ore is transformed into molten iron through a process called reduction The most common method of ironmaking is the blast furnace route In a blast furnace iron ore coke carbon and fluxes limestone or dolomite are loaded into the furnace from the top
·Ore car dumping Once the train arrives at the port the ore cars go through the car dumper The ore cars are rotated and the ore flows out into bins and then is discharged onto conveyors Stockpile The ore is stockpiled according to product type and the quality control plan The travelling stackers create 250m long stockpiles Rotary bucket wheel
·DRI production process The DRI production process involves the intimate mixing of prepared sized iron ore with a reductant which is also generally used for heating of the ore bed to the temperature needed to achieve adequate reduction rates Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or
In the Sivas Divrigi Iron Ore Concentrator 600 000 t of tailings are discarded annually There are already 1 million t of tailings deposited in ponds from the previous production activities The presence of Co Ni and Cu in the tailings makes the beneficiation of those tailings attractive
·The results show that by only adopting traditional magnetization roasting magnetic separation an iron ore concentrate containing % Fe and % P 2 O 5 at an iron recovery rate of % and a dephosphorization rate of % was produced indicating that it is difficult to effectively dephosphorize and upgrade iron by the conventional
· Falconbridge iron ore plant The Falconbridge iron ore plant was operated between 1955 and 1972 and processed pyrrhotite concentrate via a sulfation roast leach process to recover Fe in the form of a hematite product and base metals Ni Cu Co as a sulfide precipitate which is subsequently smelted Rezaei et al Citation 2017
·Returning to the overall process; that is the process for the sulfide ores and the oxide ore as I said are treated differently Direct from the pit the oxide ore is piled onto large lined leach pads and the sulfuric acid The top photo shows one of these leach pads with the new thick black plastic liner visible on the right of the pad

Mineral Spiral Concentrators Multotec spiral concentrators segregate iron ore chrome mineral sands and other high density mineral particles in sizes of less than to mm Multotec s HX3 HX5 and SC mineral spiral concentrator ranges are comprised of modular housing frames consisting of two spiral assemblies
Iron processing use of a smelting process to turn the ore into a form from which products can be fashioned Included in this article also is a discussion of the mining of iron and of its preparation for smelting Increased iron production led to a scarcity of wood for charcoal and to its subsequent replacement by coal in the form of coke
This paper presents the art of on stream particle size and elemental analysis used at iron ore concentrators followed by the results and experiences from several particle size analysis is rather common at medium to large sized concentrators Online X ray fluorescence XRF elemental analysis however is only used in some iron ore concentrators while it is a
Figure 1 Layout optimization process for chemical plants adapted from Schmidt Traub et al 1999 The impact of the financial climate In the five year period from August 2009 to August 2014 the iron ore price was above $80/t From about 2 years prior to this period Chinese demand drove project development behaviour across most mineral
