In Carajás, as the iron content is already high (above 64%), the ore is only crushed and sieved, so it can be classified by size (granulometry). In Minas Gerais, the average content is 40% iron, contained in rocks known as itabirites. To increase the content, the ore is concentrated by means of wet processing (with water).
Our heavy-duty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
The first step in making diamonds ready for sale is crushing the kimberlite ore. This important action helps to free the rough diamonds from the solid rock around them. They use heavy-duty machines to smash the ore into smaller bits, usually making them no bigger than 150 millimeters across.

Iron ore is an iron-rich ore used primarily in steel manufacturing and infrastructure construction. It has a high iron content and a variety of mineral forms and is a key raw material for the steel industry and is also used to make machinery, electronic…
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
