04-05-2021· Iron ore prices were rangebound at moderate levels for much of that year, failing to enjoy the benefits of rising steel prices. China's iron ore import volumes were slightly lower in 2018 than they were in 2017 – 1,064 million mt versus 1,075 million mt – but were more than adequate at a time when the country was removing steelmaking capacity as part of its supply-side reform agenda.
During the iron ore sintering process, the loose raw materials, mixtures of fine ore, limestone flux and coke breeze, are converted into a porous but physically strong cake, which is generally composed of four main phases: iron oxides, ferrites, most of which are a complex silico-ferrite of calcium and aluminum (SFCA), glasses and dicalcium silicate.

The main purpose of iron ore sintering is to produce a strong agglomerate for the blast furnace. This is achieved by partially melting a sinter mix at high temperature and then allowing the melt to solidify into a bonding phase for the unreacted material. The melt formation and subsequent solidification processes are highly dependent on the composition of the blended mix.
