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.

Iron Ore: The King of the Dry Bulk Shipping. The iron ore is the dry bulk cargo with the largest trading volume per year, above coal and grains. Iron ore is found in nature in form of rocks, usually mixed with other elements and after it is processed by various industrial processes, it is sold to steel companies.

The ore extracted at Carajás is rich in iron ore, an essential factor for the dry processing process. Although it took many years of research to come up with, the technique is simple: even if the ore is damp or soaked due to the rains common in the region. The increased acceleration in screening makes it possible to separate the products ...

Iron ore is different from basalt and granite. Because it contains rich iron, so apart from the crushing procedure, it also needs a dry separation process.
