Mining tailings: a perspective of the brazilian scenario, part 1: Value chain


Brazil is one of the major world mining countries. The mining sector is of great importance to the Brazilian economy because it is responsible for thousands of job vacancies. Despite its economic and social relevance, the mining activity also generates an enormous amount of tailings. Brazil’s regulatory framework on the environmental issues related to the mining sector is strong, and 14 of those regulations specifically concern mining tailings. The Samarco’s dam spill, which occurred in 2015, brought light to the issue of mining tailings, raising a number of questions in the mineral value chain. In this work, the authors provide a picture of the Brazilian mineral production chain, its tailings generation as well as the level of technological development aimed at the reuse of such tailings. The work is structured in two parts. This document highlights the mineral value chain in Brazil and the dynamics of its stakeholders. In addition, it discusses ways of increasing investments in the processes of recovery of mineral tailings.
