The 10-mineral Mohs hardness scale is a relative scale that is based on which minerals scratch each other, and its used to identify minerals. Mohs hardness | mineralogy | Mohs hardness: Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs.
Mohs hardness kit, containing one specimen of each mineral on the ten-point hardness scale The Mohs scale of mineral hardness ( / m oʊ z / ) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material
Three potential sources (from the ores, sinter, or scrap) of naturally occurring radionuclides in the slag are discussed. Iron ores due to their geochemical properties scavenge radionuclides and heavy metals resulting in only trace levels of uranium in the main raw materials for iron-making; iron ore and coke ranging of 20–30 Bq/kg and 5 Bq/kg for limestone (Cooper, 2005).
The Mohs' hardness scale was developed in 1822 by Frederich Mohs. This scale is a chart of relative hardness of the various minerals (1 - softest to 10 - hardest). Since hardness depends upon the crystallographic direction (ultimately on the strength of the bonds between atoms in a crystal), there can be variations in hardness depending upon the direction in which one measures this property.
2017/9/10Friedrich Mohs, a German mineralogist, developed the scale in 1812. He selected ten minerals of distinctly different hardness that ranged from a very soft mineral (talc) to a very hard mineral (diamond). With the exception of diamond, the minerals are all relatively common and easy or inexpensive to
One way to determine the hardness of an abrasive is to use the Mohs' hardness scale. The scale ranges from 1 to 10, with 1 being the softest (talc) and 10 being the hardest (diamond). Most abrasives that effectively achieve an anchor pattern on a surface have a Mohs' hardness of at least 6.0.

Minerals in the Olivine Series are quite hard, falling from 6.5 to 7.0 on the Mohs hardness scale. The term 'olivine' is also used for a group of related minerals that all share similar crystal structures and the same general chemical composition of X 2 SiO 4, where X can stand for iron (Fe), magnesium (Mg), calcium (Ca), manganese (Mn) or nickel (Ni).

The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). * Limonite is a commonly occurring mixture of mainly goethite, lepidocrocite, quartz and clay minerals. It can sometimes be confused with limonite or goethite with which it commonly occurs in the gossan (oxidized cap over an ore body).
Limonite is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the two principal iron ores, the other being hematite, and has been mined for the production of iron since at
