Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·The iron ore in China is characterized as "poor fine and complicated " with the limitation of beneficiation technology leading to the loss of some iron minerals in the tailings which contain an
·1 Iron ore supply and demand outline Types of iron ore Iron ores can be classified in different ways The most important has to do with the iron content In many cases ore with a total iron content of 60% to 63% or greater is regarded as high grade and ore with a lower iron content is regarded as low grade

Almost 100% of mined iron ore is used in steel production making it essential for everything from staples to buildings Beneficiation is the term for reducing the size of valuable iron ore particles and separating them from the gange unusable minerals which are then discarded There are several different methods of wet and dry separation
·Analysis of the current technical solutions for the processing of iron ores showed that the high grade ores are directly exposed to metallurgical processing; by comparison low grade ores
·iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context
·The iron ore production has significantly expanded in recent years owing to increasing steel demands in developing countries However the content of iron in ore deposits has deteriorated and low grade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter
·In conclusion iron ore processing technologies have come a long way from traditional beneficiation methods ushering in a new era of efficiency sustainability and value creation for the mining
