Vale has 19 iron ore mines and 10 industrial beneficiation plants in the QF region. These produce almost 200 million tons per year of iron ore, which represents approximately 70% of the total production in the region (DNPM, 2012; Vale S.A., 2012). Production is forecast to increase approximately 10% between 2013 and 2017, and 50% by 2030.

For the iron ore exploration and mining industries, SGS Minerals Services provides a comprehensive range of metallurgical testwork services. Our extensive global network of laboratory and metallurgical testing facilities support most of the processes that are used in the exploration and treatment of iron ore. At the broadest level, these include:
The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the ...
Equipment Design. There are three main types of thickeners/clarifiers: bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical for diameters of fewer than 100 feet.
The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the settling study. It was observed that the original slurry exhibited a low settling velocity and a turbid supernatant during the settling process. Commercial flocculating agents with anionic, cationic, and ...

Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow ...

Dec 26, 2018· Such factors multiply the decisions which must be made prior to the selection of a thickener. Most thickener designs, suitable to minerals applications, are based on the separation of -65 mesh, 2.7 specific gravity solids containing slimes. These designs are routinely adapted to coarser and/or denser materials.
The following examples illustrate the effect of the system consideration on selection of the paste thickener. Iron Ore Tailings. The integration process for the paste system at a South African iron ore plant identified the following high priority design parameters (du Toit, Crozier, 2012): A greenfield plant; tailings disposal site must be ...

Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below. High rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules.

The waste water from iron ore slurry is separated through filtration system and treated in the thickener. In the thickener, all de-dusting/scrubber return water is passed and the underflow is reused in the process. The pellet plant has a goal to achieve zero discharge norms with a comprehensive water and waste water management.
