2000. It is common practice in the mineral processing industry to use hydrocyclones for particle classification. However, classification in the UG2 platinum circuits using the hydrocyclone poses major challenges due to the differences in density between silica and chromite, the two major components of this ore.
Adding flux in HIsarna in the cyclone converter furnace (CCF – the location of solid-state pre-reduction in the process) with the addition of iron ore offers the normal production advantages such as removal of SiO 2 from the ore, but also offers early fluxing opportunity. Due to the mixing mechanics, the iron may form an early liquid slag ...

ore (e.g. grade in the heavy products) are not always considered for preconcentration. Compared to the cyclone which is limited by the crowding effect in the apex, the multi-stage separation in the Condor unit provides larger sinks product capacity. The primary advantages of using a dense medium cyclone arise when only a single stage
The 3 in 1 cyclone combines the inlet design, secondary offtake and water injector into a single unit resulting in the most efficient classification cyclone available in the market. Iron ore has a high yield to underflow and traditional dense …
To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE. Unlike the rake and …
Optimised performance found with 10° cone of novel cyclone for silica slurry. ... Generally, the particle size below 150 μm is discarded as waste (slimes) during the iron ore processing stage and stored in tailing dams. With the unprecedented demand for iron ore, the industries accumulated a huge amount of fines/slimes in tailing dams.
Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has been ...
Smelting reduction processes avoid this energy use because they make iron directly from iron ore and coal, omitting the need for coke ovens and sinter plants. The cyclone converter furnace consists of a cyclone for pre-reduction of the iron ore; the cyclone is mounted on a converter-type vessel in which the iron ore is then reduced to iron [20 ...
The results indicate that classifying iron ore fines containing 63.0% iron, 2.5% alumina and 3.5% silica through a water-injection cyclone can produce concentrates with iron grades greater than 66.0% and alumina and silica contents less than 1.5% and 2.0%, respectively, at different study conditions. The ac...
Hydrocyclones, used for classification in mineral processing, must be correctly maintained to ensure they operate at peak efficiency. If this essential equipment is not optimised, mineral processing plants will be unable to resolve any operational constraints in their systems. "Supplying only a cyclone is not good enough.
"Cyclones are divided into two main categories: hydrocyclones and dense medium cyclones, which are fundamentally different in terms of the principles that apply, and the mineral …
Proven to improve efficiency across the world's toughest iron ore, platinum, diamonds and coal separation applications, Multotec manufactures a complete range of dense medium cyclones …
Since the dense medium cyclone (DMC) was first patented in the 1940s it has become the process of choice in coal preparation, and is also widely used for upgrading iron ore and in the pre-concentration of diamonds and metalliferous and industrial minerals. It is in every sense a mature technology.
The results indicate that classifying iron ore fines containing 63.0% iron, 2.5% alumina and 3.5% silica through a water-injection cyclone can produce concentrates with iron grades greater than 66 ...
Cyclone underflow from the first stage goes to second stage cyclones, cyclone overflow from both stages are reported to the final product and cyclone underflow from second stage is sent to secondary ball mill feed. ... Application of HPGR in iron ore processing is expected to increase in the future. There is growing interest in dry HPGR ...
Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial removal of adhered alumina and free …
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 non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring …

DMS processing can be applied in diamond, coal and iron ore processing, among others. Multotec manufactures and supplies DMS processing equipment that helps drive down your mineral processing costs. ... The pretreated ore slurry is fed to a DMS cyclone or bath where separation takes place. A thick medium is introduced and the mixture is stirred ...
The molten and partially reduced iron ore forms a liquid film along the cyclone wall and drops down into the slag layer in the SRV. ... the time step is 60 s (∆t = 60 s) and 1 h calculation for the process with plant data.
