Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as quot;natural orequot; or quot;direct shipping orequot;, meaning
The iron ore tailings were characterized according to their chemical, mineralogical, environmental, and physical properties. Subsequently, the tailings were chemically stabilized using cement, lime, or steelmaking slag as binder. The tailingcement, tailinglime, and tailingslag mixtures studied consisted of 1, 2, 5, and 10% binder content, each.
Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are and, respectively, which are consistent with those of metal tailings but much higher than those of natural soils.

Abstract:Iron ore tailings reinforced epoxy composite (ITREC) is produced by reinforcing epoxy with iron ore tailings, which is the waste material derived from the beneficiation of iron ore. Two particle sizes, namely; 150 #181;m and 300 #181;m of varying percentage volume 0 to 30% at intervals of 5% were considered.
One of the chemical properties of iron is that it easily gets oxidized in open air, and this is why many compounds of iron (II) get oxidized into iron (III). Iron is a very active metal, and on reaction with oxygen and moisture in the air, it forms rust, or Fe 2 O 3 .

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
#0183;#32;The chemical composition of the IOT is given in Table 1, which is mostly SiO 2 (as high as %). According to the literature, the IOT are classified as highsilicon IOT. The SO 3 content of IOT is about %. It can be concluded that IOT is relatively inert.
#0183;#32;As industrial waste, iron ore tailings (IOTs) can be mixed with bentonite and bauxite and subsequently sintered into ceramsite. Under sintering at 1120 #176;C, ceramsite with 60 wt% IOTs, 30 wt% bentonite, and 10 wt% bauxite showed an optimal cylinder compressive strength of MPa, bulk density of kg m 3, 1h water absorption of %, and porosity of %.
Mechanical properties of concrete samples with different mixing amounts of iron ore tailings were tested in accordance with the national standard GB/T . As shown in Figure 4, standard compressive concrete cube specimens (150 #215; 150 #215; 150 mm 3 ) were fabricated according to different amount of iron ore tailings.
Our sincere gratitude goes to Greg Hudson and David Eastman of Mount Gibson Iron, Perth who assisted by providing the iron ore mine tailings for this research. The authors would also like to extend their appreciation to Lee Gough, Gary Wheeler and Dave Farrar, all of MinAnalytical Laboratory Services Australia Pty Ltd, for their assistance in conducting the XRF analysis through their facilities.
Iron compounds are produced on a large scale in industries. Ferrous Sulfate, FeSO 4 7H 2 O and Ferric Chloride, FeCl 3 are two of its compounds which are produced on a very large scale. One of the chemical properties of iron is that it easily gets oxidized in open air, and this is why many compounds of iron (II) get oxidized into iron (III).
