Processing based on natural moisture - Vale

2021-11-9  Vale has developed a revolutionary technique for processing iron ore in regions of high rainfall, which does not use water in the process. This technique avoids the need to build tailings dams, reducing impact on the environment. Called natural moisture or dry processing, it was put into practice, in 2008, on a trial basis at Carajás, Pará.

Processes and Procedures in the Extraction of Iron ...

2021-2-15  The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
