Hard rock mining refers to various mining techniques used to excavate hard metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin …
However, the iron ore from Kashenyi hill has lower iron content (about 6l% Fe) and higher gangue content (5% SiO 2 and 6% Al 2 O 3) at low concentration of the deleterious elements (0.02% P and 0.003% S). According to commercial standards for crude iron ores, this ore can be defined as medium-grade ore.
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. ... treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500-mesh for liberation of the iron minerals from the siliceous gangue.
we are mainly deals with production of ultra pure iron concentrate,raw iron ore and its related mineral separation process. Iron ore concentrates are used as a metallurgic raw material in iron smelting with grade between 70 and 72.3% Fe.

However, when the gangue minerals are iron-bearing silicates, the strong interaction with starch can occur on these minerals since they have the same surface behaviour as iron oxide.
gangue minerals in iron ores - accmet-project.eu. Gangue - Wikipedia, the free encyclopedia. In mining, gangue (pronounced "gang which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being Iron
Automated Hyperspectral Logging. The successful development of iron ore resources is fundamentally linked to our ability to accurately identify not only multiple species of iron oxide minerals, but also sub-species, phases (eg. ochreous vs. hard) and associated gangue minerologies.
Dec 06, 2015· The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressing. It is a necessary, and often significant, aspect of mining . It can be a complicated process, depending on the nature of the minerals involved.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of direct reduced iron (DRI) and in blast furnaces for the production of hot metal.

Mining waste refers both to gangue (waste rock) and to tailings arising in different parts of the production line. Extensive gangue heaps, among other things containing iron and rare earth elements, at old mines in Idkerberget, Bergslagen.
This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy .
Sep 30, 2012· The obtained iron ore materials are moved to flotation desulfurization process, then to weak magnetic separation. The obtained product is iron ore concentrate. And low iron content material is ...
The gangue – ore components of no commercial value – has to be removed before processing. XRD finds typical gangue minerals: silica and alumina from quartz, clay, mica, feldspar, or carbonates. They may be removed in the beneficiation by washing, or magnetic or gravity separation, before further processing of the ore.

SEM analysis of iron stones indicated that ooides contained major proportion of iron ore and that they are finely disseminated with gangue minerals. Fig. 4 is a combo of five images showing over-mapping of Si, Fe, and Mg elements present in the ooide in the first image.
The genesis of these ores is considered as due to a residual concentration of the iron oxides after leaching of the gangue minerals during the Cenozoic weathering. The genesis of the hard high-grade ore is more complex and not well understood.
