Resumen
Mining in Brazil has been hibernating for a long time with regard to new technologies, this is largely due to the interference of professionals who did not allow it, much less encouraged the development of new solutions for their operations. They often adopt projects that work in other operations in the world, disregarding the particularities of our climate, culture, type of ore and, mainly, not valuing national manufacturers. Nowadays, mining has been forced to innovate, due to successive accidents with a high environmental impact and loss of life. The sector has been transformed through technologies and process innovations, which will allow for a more sustainable operation with less impact in the near future. The main objective of this work was to find innovation opportunities for the construction and development of equipment, solutions or services, which could guarantee the survival and sustain the growth of a mature company, with more than twenty-five years of existence. Motivated by a moment of financial instability, it was forced to reinvent himself. Documentary research and evaluations were carried out within the mining companies, seeking solutions that directly impacted operations with significant gains. The objective was achieved, resulting in three solutions with technological bases for the concentration of metals such as gold (Au), by means of a centrifuge suitable for very fine gold ores, characteristic of the current ones present in Brazil. Elimination of the use of mercury (Hg) for gold recovery, the main liability for small miners, being developed a system for gold recovery, by means of leaching, with expressive results and very low processing times, allowing a cultural disruption of the use of mercury to obtain gold. Finally, a solution for the treatment of the effluent generated by this process and by the mining companies, mainly with the presence of cyanides and arsenic, with a significant reduction in costs, reduction in the use of chemicals and in some results, even eliminating them. These solutions formed a technological package, which will mainly allow small miners, to have an operation with high levels of efficiency and totally sustainable processes.
