This is a new product developed by Vale over the course of almost 20 years. It is a mixture of iron ore and a binder solution, which holds the particles together and gives the product strength. It is one of the ingredients used in steel production, replacing sinter, pellets or lump ore in blast furnaces.

The briquette can also be used as a charge for the blast furnace (BF-BOF). Direct reduction is one of the routes used in steel production. It is considered cleaner than the blast furnace route, because it uses natural gas instead of coke - an input obtained from mineral coal - and, therefore, emits less carbon and other Greenhouse Gases (GHG).

These hot gases rise up in the blast furnace and cool down. From a maximum of 2000 °C at the level of the hot-blast nozzles (tuyere), the temperature decreases to around 200 °C up to the throat. At this temperature, the filled charge are first dried and preheated. This zone of the blast furnace is therefore called the preheating …

A blast furnace is a block that smelts ores, raw metals and metal armor and tools twice as quickly as a furnace but cannot smelt anything else. It also serves as an armorer's job site block. A blast furnace can be picked up using any pickaxe. If mined without a pickaxe, it does not drop. Blast furnaces drop their contents when broken. Blast furnaces can …

The blast furnace is a continuously operating shaft furnace based on the counter-current flow principle. At the top coke and burden (sinter, pellets, lump ore, and flux) are charged in alternating layers. Charge materials descend under the influence of gravity. In the lower part of the furnace, hot blast from hot stoves is injected through tuyeres.
