3/24/2021· It has been found that the main iron-bearing mineral is hematite, which contains 69.02 to 70.35% of iron distributed in the ore. Magnetite and hydrogoethite account for 16.71–17.74 and 8.04–10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides is very insignificant.Read More
6/1/2002· Two typical weakly magnetic iron ores in China, namely East Anshan (EA) hematite ore and Tiekeng (TK) limonite ore, were used in this work. They were obtained from the East Anshan iron mine located in Liaoling province, and the Tiekeng iron mine in Jiangxi province, respectively.Read More
Magnetite and hematite are common iron-oxides, being found in sedimentary, metamorphic and igneous environments and being associated with a wide variety of deposits styles, including orogenic gold, iron-oxide copper-gold and iron-ore deposits. While the magnetic and mass properties of magnetite and hematite have beenRead More
SUBSTANCE: method for enrichment of hematite ores includes stage process of crushing and magnetic-flotation process of enrichment, including three stages of crushing, magnetic separations of the first and second stages accordingly after the first and second stages of crushing, flotation of magnetic product of the second stage of magnetic separation after the third stage of its crushing.Read More
Hematite ore deposit loses magnetic susceptibility as it oxidizes. So, with the absence of significant magnetic anomaly, it doesn't respond properly to magnetic method. As hematite ore deposit can be conductive due to its porosity. This characteristic leads electrical methods,Read More

A number of magnetic separation processes are used to study preparability of two main hematite-magnetite and magnetite-muscovite ore types extacted it the Abagas iron ore deposit. The dry magneticRead More
effect of structural parameters of the matrix on separation performance of ﬁne hematite ore tailings in Northeast China, and the numerical analysis of the magnetic induction properties of different kinds of magnetic matrices based on three-dimensional structural characteristics.Read More
7/1/2015· In practice, HGMS is widely used to preconcentrate fine weakly magnetic ores, and is processed by flotation or gravity processes to produce a marketable highRead More
by a coincident magnetic and gravity anomaly [Esdale et al., 2003]. The large 170 GU (17 mGal) gravity high arises from the hematite-rich ore body. The nearly coincident, but broader, 1000 nT magnetic anomaly was originally inter-preted as arising from a deeper body, such as a mafic intrusion, but appears to be explicable by induced magne-Read More
The giant Olympic Dam hydrothermal Cu‐U‐Au‐Ag ore deposit, which occurs in an enormous volume of semimassive hematite and hematite breccia within brecciated Mesoproterozoic granite 200 km to the southeast of the Mount Woods Inlier, was identified by a coincident magnetic and gravity anomaly [Esdale et al., 2003]. The large 170 GU (17 mGalRead More
Paramagnetic minerals (hematite, biotite, ilmenite, etc) are simply captured by “TIGER” PULLEYS’s powerful magnets. MAG 1.10/15 & MAG 3.10/15 magnetic separators are particularly indicated for the iron removal of fine particle size products (typically from 0,1 to 1,8 mm). 3 SEPARATION STAGESRead More
After microwave treatment, the samples were subjected to the separation in magnetic field with maximum induction of 0.17 T, where at 15 min heated sample the 97.6% recovery of Fe was obtained.Read More
