Factory in MG, Located at the Pico Mine, Inaugurated on Tuesday, the 17th, is a Pilot Plant for Products for Civil Construction, Based on the Magnetic Concentration of Low-Grade Iron Ore, Without Using Water.
After the tests, it is assumed that the unit installed at the mine in MG will prevent about 30 thousand tons of mineral waste from being dumped into dams or piles, transforming them into almost 4 million products for the civil construction sector, including concrete blocks, fencing, pipes, and similar items.

Vale has been overseeing studies on the application of mineral waste since mid-2014, focusing on its use in civil construction to replace natural sand. According to the UN, sand is the second most exploited raw material in the world, only behind water. Due to its scarcity, the material is subject to illegal and predatory extraction.
Dutra highlights: “The sandy mineral waste from Vale is a result of mineral beneficiation, and it has a high silica content and a low iron content, also having the advantage of high chemical and grain size uniformity.”
