A process for treatment of anthracite coal when combined with cinders and/or klinker type ash produced by old cleaning plant boilers comprising sizing of the mixture and magnetic separation of the ash from the mixture thereby improving the combustion value. Use for treatment in existing anthracite and cinder waste piles is disclosed.
(2) The optimum process of the parameters of the semi-smelting reduction and magnetic separation process should be w (CaO)/ w (SiO 2) ratio of 1.25, temperature of 1425 °C, time of 15 min, anthracite ratio of 11.92 wt %, CaF 2 ratio of 1.96 wt %, and magnetic intensity of 4000 Gs.
Apr 10, 2019· Effects of the anthracite dosage on magnetic separation. In the presence of 20 wt% the red mud, the ferronickel products obtained as a function of the anthracite dosages are shown in Table 3. As shown in Table 3, an appropriate increase in the anthracite dosage promotes the co-reduction effect. With increasing the anthracite dosage exceeding 16
May 06, 1986· BACKGROUND OF THE INVENTION. I. Field of the Invention . The present invention relates to a process for treatment of anthracite coal. More particularly it relates to magnetic separation of previously processed anthracite coal from klinker type ash or cinders, which is an industrial waste product of pre 1960, anthracite treatment centers or coal breakers.
Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 .A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.
After the magnetic separation, the synthesized magnetite concentrate obtained was subjected to pelletization at different temperatures and RT to optimize the process parameters. Since pelletization is an oxidation process, the magnetite phase present in the pellet after induration converted to the hematite phase minerals, which can further be
Able to be recovered by magnetic separation after coal washing; Non-fouling; subsequent treatment stages are unaffected by trace deposits; High purity; free of hematite, sulphides, etc. Specifications. Ferrous iron oxide magnetite (Fe304) is the concentrate of magnetite ore that contains 96% magnetics.

A Preliminary Investigation into Separating Performance and MDPI Mar 2, 2018 The Highgradient magnetic separation HGMS technique is widely used in the preparation of fine hematite concentrate in iron ore concentrators under the current the design of the screw thread generates an axial magnetic
temperature of 1300 C, the anthracite dosage of 26%, and the reduction time of 90 min. Moreover, the separation results revealed that metallic iron and TiN can be separated precisely through grinding and magnetic separation. Therefore, the puriﬁcation of impure TiN is the key technology of this process.

Particulate mixtures of non-magnetic or paramagnetic materials are separated by selectively coating the surfaces of a component or components of the mixture with a magnetic fluid. Thereafter, the particulate mixture is subjected to a magnetic separation yielding a magnetic fluid-coated fraction and a non-magnetic fraction. The process is especially useful in mineral beneficiation wherein a
Magnetic Separation of Briquettes The effect of coal type on the reduction followed by mag-netic separation of high-phosphorus oolitic hematite ore was investigated. The experiments were performed at conditions of roasting temperature 1 200°C, roasting time 40 min and C/O ratio 1.0. The experimental results are shown in Fig. 2.
A soil remediation method based on magnetic beneficiation is reported. A new magnetic solid chelator powder, [email protected] (core-shell Fe 3 O 4 @SiO 2 nanoparticles coated with iminodiacetic acid chelators), was used as a reactive magnetic carrier to selectively capture non-magnetic heavy metals in soil by chelation and removal by magnetic separation. [email protected] was prepared via inorganic-organic and
, much of the dense, magnetic iron particles accompanied the coarse product which then becomes a superior feed for separation of the iron-bearing particles by magnetic or other methods. This secondary process would lead to recovery of a magnetic-iron concentrate and a high carbon . product for recovery of lost heating values.
charcoal, anthracite, water gas, reformed natural gas, ammonia or hydrogen decomposition) to generate the sponge iron. The reduction process consists of two procedures, which are primary reduction (solid carbon reduction) and secondary → Magnetic Separation → Entering Secondary reduction furnace
Dec 16, 1975· Magnetic separation of particulate mixtures is highly developed and long-practiced. The technique may be practiced as a wet process, such as in a water slurry, or may be used to separate a dry particulate mixture. Magnetic separation is cheap, highly selective, efficient and lends itself to both small scale and large volume uses.
