All over the world, miners are reducing the use of dams, which means reducing millions of tons of mining tailings and less risk to the environment. In Brazil it is not different. Recently, the National Mining Agency (ANM) banned 45 dams that used the so-called upstream method — in which the containment barrier receives layers of the mining tailings material itself.

Dry mining eliminates the use of chemical products such as mercury and cyanide, which avoids possible soil pollution, and does not require the creation of a dam, as it does not produce earth waste. This process also aims at a water economy, where the extraction of a ton of gold uses around 500 liters of water, according to the average for the sector.
