| titleOfInvention | Method of preparing charge for producing fluxed iron-ore pellets |
| abstract | The invention relates to the field of preparation of iron ore to metallurgical processing and can be used in the mining and metallurgical industries in the production of fluxed pellets from finely ground iron ore concentrates. The purpose of the invention is to provide high strength characteristics of the pellets of a given basicity by creating a strong bonding skeleton of lime hydroxide crystals in the pellets, as well as accelerating the hydration of lime in the charge. Into the stream of wet iron ore concentrate, quicklime and finely divided limestone are introduced, the amount of the latter being determined from the equations, 0-55 ° C. & &deg; -b (Si02), (Si02), -CaO; (l-0.003FA) / Ca02-b (biOjJ2 (0.75CaOc6.

Mix the mixture and release the lime before hydration by 85-90% before subsequent pelletizing, drying and roasting.
