Jun 21, 2018· After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm. This is also known as lump ore. In addition to lump ore, fine ore (approx. 1 mm) and ground ore (ore powder) (approx. <0.1 mm) can also be obtained by crushing and grinding.Although iron is present in most common rock types, it is generally uneconomic, or in forms that are not read-ily processed. Iron-ore deposits generally have >25 wt % Fe, usually in the form of hematite (Fe 2 O 3), magnetite (Fe 3 O 4), goethite (FeO(OH)), limonite (FeO(OH)•nH 2 O) …

The most easily seen ore of iron that is found is hematite. Now to find in which ore of iron, the iron content is maximum we can use mass percentage.

The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.An ore deposit model is a conceptual and/or empirical standard, ideally a population of natural phenomena, embodying both the descriptive features of the deposit type, the larger ore-bearing environment, and an explanation of these features in terms of geological, and hence of …
