High grade iron ore after dry or wet sizing at the ore mine is that ore which contains higher than 62 % of Fe. This ore is normally known as 'natural ore' or 'direct shipping ore' (DSO). This ore can be directly used in the production of iron and steel.
The two wet processing plants at Iron Knob and Iron Baron, with a combined throughput of 950 tonnes per hour, were designed, manufactured and delivered within 18 months from signing which was unprecedented for an Australian mining project of this nature.
WHIM is the short acronym for Wet High Intensity Magnetic Separation . At present, most iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet lowintensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to 25 percent ...
Wet Permanent Magnetic Drum separator is a kind of magnetic separator often used in iron ore concentrators. It is suitable for separating high magnetic minerals. According to the different structure of the tank, it can be divided into three types: downstream type, countercurrent type, and semicountercurrent type.

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % to 63 % Fe) hematite iron ore. The wet process consists of multistage crushing followed by different stages of washing in the form of scrubbing and / or screening, classification etc., but the advantage is only partial removal of adhered alumina and free silica in the calibrated lump ...
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the nonmagnetic type which after a reducing roast are amenable to magnetic separation.
Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and process is considered an excellent option for the storage and transport of said materials. The technology is widely used in the powder metallurgy engineering ...
3 Screening machines for iron ore and coal. The crushing and screening systems for iron ore processing vary widely, depending on whether a magnetite or hematite deposit is being mined. While good quality magnetite is now dryprocessed, hematite from deposits below the water line requires wet processing due to sticky quartz and clay contaminations.

Proc ...
Mineral Drying. Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product. While mineral dryers may appear the same as other industrial dryers, they are typically built ...
The Reading WHIMS range has set the industry's performance benchmark for wet magnetic separation of fine minerals. Talk to the team today about how we can help to: Upgrade iron ore fines (10micron to 1mm) Recover fine iron ore from tailing streams Separate ilmenite from heavy mineral sand concentrates Reduce downstream processing
The primary objective of beneficiation for nonmetallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a highintensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.
The iron ore processing industry produces usable concentrations of ironbearing material by removing nonferrous rock (gangue) from lowgrade ore. In the United States, predominant iron ore is taconite which is a hard, banded, lowgrade ore. Ninetynine percent of the crude iron ore produced in the United States is taconite.
Download. Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.
Most iron ore processing takes place in the fine particle size ranges and is often carried out on a wet basis. However, some iron ore resources are located in dry areas where adequate water supply is very difficult to obtain and hence dry processing is the only option.
Water scarcity dictates to limit the use of water in ore processing plants particularly in arid regions. Since wet grinding is the most common method for particle size reduction and mineral liberation, there is a lack of understanding about the effects of dry grinding on downstream separation processes such as flotation.
