Chemical analysis equipment is used to determine, characterize, and quantify chemical components in gas, liquid, and solid samples. Bioanalysis, nanotechnology, clinical chemistry, environmental and materials analysis, and forensics represent a few of the many areas of use for chemical analysis …
The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (southwestern Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.
Available world iron ore resources. Iron is the most abundant element on earth but not in the crust.  The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.
Performing elemental analysis of minerals is one of the most important routine works in Earth sciences. Among the numerous analytical techniques for elemental analysis, beam methods (especially electron microprobe analysis) are the most common and important methods. Further improvements of the technical equipment and adjacent software

Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).

Cast iron breaks when it is loaded with significant pressure, although the carbon content in cast iron makes this metal good for casting. This type of cast iron is called grey cast iron, and its main characteristic is the greycolored carbon flakes in its composition. To produce cast iron, iron ore is deoxidized in a blast furnace.
