Desulfurization of low rank coal co-pyrolysis with reduced ...

10/12/2018  In this paper, low rank coal co-pyrolysis with reduced iron powder (Fe powder) and then followed by dry magnetic separation was used to reduce the sulfur content of low rank coal. After dry magnetic separation, the organic sulfur content can be reduced from 2.00% for low rank coal before the pyrolysis to 0.33% for the coal after 700 °C co-pyrolysis with Fe powder at the coal/Fe-powder mass ratio of 4:1. However, the organic sulfur content can be only reduced to 1.28% for the coal

The dry magnetic separation for magnetite concentrate obtained was studied first. In the tests, two magnetic intensities (MI) were used: low-level (0.13 T) and high-level (0.26 T). As shown in Figure 3, then low-level MI was used, the major part of the raw CFA concentrates into the non-magnetic fraction (I). The yield of the magnetic fraction (I) was not more 0.54%. The recovery of magnetite did not exceed

Dry coal preparation without the use of water • STEINERT

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. Since the x-ray technology is capable of detecting atomic differences in the rock, the almost pure carbon in

Magnetic Separator - an overview ScienceDirect Topics

Dry HGMS processing has the advantage of a dry product although classification of the pulverised coal is required to ensure proper separation. Small particles tend to agglomerate and pass through the separator. It has been shown that individual particles of coal in the discharge of a power plant pulveriser flow freely and hence separate well only if the material below about 10 µm is removed

This creates a distinct advantage to using rare-earth dry magnetic separators: the ability to produce a variety of TiO 2 products rather than a simple mag/non-mag split. Additionally, rare-earth dry magnetic separation circuits are typically lower in capital and ongoing maintenance costs, and are less complicated to operate than WHIMS.

Dry separation of iron minerals from low-grade coal

15/10/2015  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

New Highly Efficient Dry Separation Technologies of

It has been proved that high-intensity magnetic separation and triboelectrostatic separation are effective methods of cleaning fine-grained high-ash coal. It has been determined that the efficiency of using these methods for non-combustible mineral fractionation increases after thermo chemical heat modification of high-ash hard coal. Combining high-intensity magnetic separation with triboelectrostatic separation

Magnetic desulfurization is an attractive physical method of coal cleaning which has been studied for a quarter century. High‐frequency selective heating of coal to convert nonmagnetic pyrite to moderately magnetic pyrrhotite has been suggested to enhance separation. Despite predicted feasibility, some successes have only recently been by:
