Special attention is paid to theSintering of ore fines appears to be a most suitable method of agglomeration under present condition. In the present case sintering characteristic of Mn Ore fines from MOIL, Nagpur has been studied in a continuous strand type sintering pilot plant of 20 MTday capacity. The sinters so produced were charged in electricJun 11, 2019 World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.Preparation ofthe Ore Up to 1987, the process consisted ofopen-castmining fol lowed by various stages of crushing and screening before the ore was dispatched to the consumer. With the exception ofsmall uses in the uranium. battery, chemical, and agricul tural industries. sales of manganese are are largely depen dent on steel production.
