For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.

silver. silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration, which results in its reflecting all ...

In BFI, the iron ore is reduced to iron through a chemical reaction with carbon monoxide generated from coke. Coke reacts with oxygen in the iron ore to produce carbon monoxide, which acts as the reducing agent to convert iron oxide into iron: Fe 2 O 3 + 3·CO → 2·Fe + 3·CO 2. BFI is a carbon-intensive process.
