Rio Tinto Iron Orex27s low-grade ore beneficiation plant in the Pilbara was commissioned in 1979. Initial engineering, design, and construction were undertaken by KBR Kellogg Brown and Root and Minenco RTIO information provided to author, 2013. The plant separates closed-circuit crushed ROM into 31.56.3mm and 6.30.5mm streams for feeding their DMS drum and cyclone plants, respectively Figure 10.5.Get A Quote
An overhead view of the plant is shown in Figure 10.6 showing where the screening house and the two DMS buildings fit into the overall plant layout.
The particle sie is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
general way the scope of mineral dressing or ore beneficiation is twofold 1. It helps in... comparison between jaw and gyratory crushers is given in the table 2.4. Ore dressing - definition of ore dressing by The Free Dictionary.
Media recovery is by single-stage wet low-intensity magnetic separation drums Magnapower. 200mm densifiers are used to densify heavy media.
To evaluate an iron ore resource, develop processing routines for iron ore beneficiation, and understand the behavior of the ore during such processing, extensive mineralogical characteriations are required. For calculating mineral associations, mineral liberation, grain sie and porosity distribution, and other textural data, reliable imaging techniques are required.
Automated optical image analysis OIA is a relatively cheap, robust, and objective method for mineral and textural characteriation of iron ores and sinters. OIA allows reliable and consistent identification of different iron oxide and oxyhydroxide minerals, e.g., hematite, kenomagnetite, hydrohematite, and vitreous and ochreous goethite, and many gangue minerals in iron ore and different ferrites and silicates in iron ore sinter. OIA also enables a distinction to be made between forms of the same mineral with differing degrees of oxidation or hydration.
To reliably identify particles and minerals during OIA, a set of comprehensive procedures should be automatically applied to each processed image. Generally, this includes next stages image improvement, particle and mineral identification, particle separation, porosity identification, identification of unidentified areas, and correction of mineral maps. This is followed by automated measurements of final mineral maps and statistical processing of results.
High resolution, imaging speed, and comprehensive image analysis techniques of modern OIA systems have made it possible to significantly reduce the cost and subjectivity of iron ore and sinter characteriation with a simultaneous increase in the accuracy of mineral and textural identification.
