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 Caraj225s, Par225.Chat Online
Experience of manufacturing and installing over 2000 ore processing project globally and enjoys a high reputation in more than 160 countries and regions in the world.
Today, most of our iron ore production about 60 is through dry processing. the natural moisture processing is used at caraj225s and serra leste mines, at s11d eliezer batista complex, in par225, and at several plants in minas gerais.
The processing takes place in three stages sorting, concentration and pelletizing. once the iron ore concentrate has passed the pelletizing plant, the end product small, round iron ore balls, known as iron ore pellets is ready for onward transport to our customers.
