I was doing my homework to find mining info about iron ore mining processing.

Drilling
As an universal practice, iron ore is dislodged by drilling blast holes according to a particular pattern which depends on the bench height, the hole diameter, nature of rocks, the drilling machinery deployed and the types of explosives used.
Blasting
Iron Ore blasting is the controlled use of explosives (or other methods such as gas pressure pyrotechnics or plasma processess) to excavate, break down or remove rock. It is practised most often in mining, quarrying and civil engineering such as dam construction.
Excavation
As the quantum of excavation in iron ore mining has increased year by year the technology has undergone a sea change in all aspects of mining activity like loading, hauling and transportation.
Iron Ore Crushing & Screening
In earlier mechanised opencast mines, processing involved was crushing to required size and separation of various products by dry screening. With the increasing emphasis on cleaner product, wet screening has come in vogue in place of dry screening. Small capacity crushers have now given place to large capacity crushers with improved reduction ratio.
Iron Ore Grinding
Iron Ore Grinding Process is an optional process which makes preparation for the iron ore beneficiation.China's iron ore grinding process, the majority of two-stage grinding process, a small processing plant to use more grinding process. Basically, after grinding using a hierarchical spiral classifier. To improve efficiency, some concentrator Hydrocyclone replace the second spiral classifier.
Iron Ore Beneficiation
Very low grade Iron ore cannot be used in metallurgical plants and needs to be upgraded to increase the iron content and reduce the gangue content. A process adopted to upgrade ore is called Beneficiation. Iron ore is upgraded to a higher iron content through concentration. Iron ore is being beneficiated all round the world to meet the quality requirement of Iron and Steel industries.
Sintering and Pelletizing
Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the fee.Accordingly the processes are known as Sintering and Pelletising respectively.
Iron Slag Recycling
During washing and sizing of the ore, slimes with less than 0.21 mm size are generated and discarded into the tailing pond. Huge quantity of slimes are being generated in every year during the processing of hematite ore and lost as tailings containing around 48-62% of Fe. This possess great amount of pressure on environment and on conservation issue.
