CSN seeks innovative projects that offer alternatives for the sustainable destination and use of the tailings from Casa de Pedra mining site. This residue is fed into the filtration process and the filtrate content which is approximately 15% moisture is pumped and subsequently loaded and transported to the tailing disposal stacks. Its main characteristics are 95% passing material in 0.15mm and the iron and silica elements are respectively 20% and 70%. We are looking for innovative solutions capable of dealing with residues in a way that reduces the costs of the transportation and stacking process and is environmentally friendly.
LOCATION OF THE PoC: Mineração Casa de Pedra
We are looking for solutions capable of investigating the internal behavior of the solid fill and to monitor the changes of the structure in a continuous way, which allow to analyze trends of displacement, infiltration, internal erosion (pipping), water level, through 3D modeling of the structure and constant feedback of information.
