It follows from Table 1 that the TI values of Muko ores are between 88 wt% and 93 wt%, which is significantly higher than the stipulated 70 wt%. Therefore, the ores from all Muko deposits can be handled, loaded, and transported .
pelletizing iron ore rotary kiln
Iron ore pellets are marblesized balls of iron ore that are fused with clay for transportation, and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from a lowgrade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.

A full survey of the laboratory and blastfurnace tests on 2 types of acid pellets is given. From the laboratory tests out in an atmosphere containing hydrogen, it appears that type B, produced out of magnetitic ores, has a far better low temperature disintegration index and a lower reductibility index than type A, produced from a hematite/magnetite mixture.

The binding of iron oxide grains by bentonite clay to form pellets is a complex process, with a large number of variables, many of which have never been adequately studied. Current practice for pelletizing iron ore concentrates was developed in 1950's during which bentonite clay was practiced as a binder and since then it has remained

The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing. The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets.
Pelletizing of Sishen concentrate J r n a SAIMM
Briquetting is one of the oldest iron ore agglomeration methods, but it has since been replaced by sintering and pelletizing. Briquetting is the process where a mixture of fine ore (concentrate) and binder is compressed in a briquetting die to form a product with uniform size and shape. Developments of briquetting techniques, such
The Making of Iron Steel SEAISI
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
