Effect of Iron Ore Concentrate on Sintering Properties

Compared with conventional sinter feed, small-sized iron ore concentrate contains a lower alumina. Recently it is more popular to be applied in commercial sinter plants to decrease the alumina content in sinter or combined with a high alumina low grade ore to reduce the production cost of sintering.

Sinter plant Wikipedia

Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum.

What is sinter feed? AnswersDrive

Sinter feed is an iron concentrate containing fine particles and moisture and, being similar to iron ore fines,”1 is at risk of liquefaction, resulting in cargo shift and loss of stability. Liquefaction is believed to have resulted in a number of casualties, causing the loss of many seafarers' lives.

Shift-to-quality in the iron ore market CRU

The implications of China's 'shift-to-pellet' go beyond the pellet/pellet feed market. Chinese mills typically blend higher-Fe, higher-silica domestic fines with lower-Fe, lower-silica material from Australia to make sinter. As more domestic concentrate is used to make pellet in the long-run, smaller volumes will be available for sintering.
