An effective means of dry coal beneficiation is offered by our STEINERT XSS® T EVO 5.0 X-ray sorting system based on 'dual energy' x-ray transmission. This allows ash content to be reduced without the use of water, while specific contaminants such as sulphur can be accurately removed.
Eriez Dry High Intensity Rare Earth Roll Magnetic Separator . With the ever increasing demand for high-purity feedstocks used in manufacturing, Eriez offers its Dry High Intensity Rare Earth Roll Magnetic Separators. These provide maximum efficiency in the separation of weak magnetic particles for product purification applications.
Fines dry magnetic separation promises a new alternative. Even before the 2019 disaster, Vale was busy looking for alternatives to wet magnetic separation. The eventual breakthrough the company made came too late for the victims in Minas Gerais, but it could transform life for other miners and the local environment.
The dry magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size of 3mm or less. It is also used for iron removal of coal, non-metallic minerals, building materials and other materials.
[Show full abstract] scrubbing, wet screenning and dry magnetic separation respectively on the -25+3 mm middlings, the product containing 39,50% B2O3 was produced with the recovery of 94,37%, -25 ...
The separation of pyritic sulfur and ash forming minerals from dry crushed coal in a small, cyclic, high gradient magnetic separator over a range of each of the process parameters was tested. A band of operating conditions that affected reductions of the mineral contaminants and recoveries of the heating value comparable to gravimetric separations was defined.
Global Fourth-generation Vertical Ring High Gradient Magnetic separator (Oil-water complound cooling) Application: This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm ( – 200 mesh of 30-100 %) of fine grained red mine (hematite) limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore ...
magnetic induction of up to 5 T can be generated, a brass chamber with SUPERCONDUCTING MAGNETSFOR COAL SEPARATION 21 rectangular cross section (50 x …
An improved air jig apparatus and method is disclosed in which a dry magnetic separator is used to separate paramagnetic and ferromagnetic minerals from the dust component of coal cleaned with the air jig. The cleaned product of the dry magnetic separator is combined with the cleaned product of the air jig thereby improving both the quality and the quantity of the unmodified air jig product.
The Magnetic Fraction of Coal Fly Ash: Its Separation, Properties, and Utilization . M. J. MURTHA and G. BURNET . Ames Laboratory USDOE and Department of Chemical Engineering and Nuclear Engineering Iowa State University, Ames, Iowa 50011 A laboratory-size electromagnetic device has been built to separate the high-iron magnetic fraction from ...

The 6th International Heavy Minerals Conference 'Back to Basics', The Southern African Institute of Mining and Metallurgy, 2007. A discussion of magnetic separation techniques for
Dry separation of iron mineral from low-grade coal-series kaolin in Hubei Province of China was investigated. The structure and chemical composition of the kaolin ore were determined by X-ray diffraction (XRD) and X-ray Fluorescence (XRF) analyses. The narrow particle size range classification, dry magnetic separation and calcination were carried out to evaluate the particle size …
