Brazilian iron ore miner Samarco and the EMBRAPII Unit in Sustainable Mining, of the Federal University of Ouro Preto (UFOP Escola de Minas), have signed a contract to conduct studies on new ways of using sandy iron ore tailings in the construction production chain. The partnership, signed in October of this year, is the unit's inaugural project after the university's accreditation to EMBRAPII with a focus on sustainable mining. In addition to the development of technologies for the use of tailings, the initiative aims to generate business opportunities for the region of Ouro Preto and Mariana, promoting the circular economy, considering the vocation of the manufacturers of these territories. The partnership is aligned with Samarco's purpose of making mining different and more sustainable and sharing value with society. Training will also be promoted for entrepreneurs to use the technique, providing diversification and sustainable business development. The UFOP School of Mines - EMBRAPII Unit in Sustainable Mining - will define the trace of ore tailings to be applied in the production of precast and masonry, manufactured from sandy tailings. The performance of this unit is focused on sustainable mine operations, sustainable processes in mining, treatment and sustainable management of waste and water. It highlights the environmental and economic benefits of the blocks. The blocks consisting of sandy tailings from mining, in addition to contributing to the reduction of the disposal of this material in the environment, will increase the range of alternatives of construction materials of low cost and similar efficiency. After obtaining the appropriate certifications, the block initially manufactured to be used in paving of roads will be able to be produced on a large scale and marketed, contributing to the local economy from which it can be produced Among the projects planned by the initiative, the material produced will be destined to the manufacture of blocks that will be applied in the paving of the Purification road, which connects the district of Antônio Pereira to the Morro de São João neighborhood, in Ouro Preto, in the last stage of the works, expected to be completed for the second half of 2023. The initiative also foresees the evaluation of the use of sandy ore tailings on other fronts, according to economic potential, technical feasibility, environmental, social and financial costs, as well as mapping manufacturers, for analysis of proposals for sustainable alternatives for localities, thus fostering the ecosystem of the region. The contract was signed through the Research Development Foundation (Fundep).
