Iron ores can be grouped into types of similar geological occurrence, composition and structure. The following is a simplified classification which is based on genesis of the deposits and geological environment. It shows the main modes of occurrence of iron ores as well as it illustrates the varied geology of iron ore deposits.
This study involves the study of ore reserve estimates and the modelling of ore body (Use of SRPAC). The importance of accurate ore reserve estimates has always been recognized in the past. Mining companies obviously need accurate ore reserve estimates since the quality of the estimate may directly affect the company's profitability.

In the first step, carbon and oxygen react to form carbon monoxide:2Cs +O2g -->2COgIn the second step, iron (III) oxide and carbon monoxide react to form iron and carbon dioxide:Fe2O3s + 3COg --> 2Fes +3CO2gSuppose the yield of the first step is …
Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable …

The first step in this process is crushing and grinding the ore to a fine powder. This powdered ore is then subjected to a process called magnetic separation, where magnets are used to separate the iron particles from other minerals present in the ore. This helps in purifying the iron ore and increasing its iron content.
