Abstract:
Generating high iron containing concentrates is an important goal to ensure the efficiency of their Direct Reduction subsequent treatment in the framework of sustainability. This was the main objective of Fundação Gorceix when undertaking, through its Mining and Metallurgy Department two major industrial iron ore projects: (1) BAMIN's Pedra de Ferro project, which plans the production of 25 million tons of pellets per year, in the State of Bahia, outside the Ferriferous Quadrangle, with an expected start up in 2025 and (2) Compact Ores Arcelor Mittal project–Serra Azul Mine, in Minas Gerais state.
During the course of the projects a complete research investigation was carried out including mineralogical characterization, bench scale tests and pilot plant studies. The major result of the work was the generation of a premium concentrate for Direct Reduction with iron content as high as 66.5% and with a high competitive metallurgical recovery. The industrial processing flowsheet in a compatible industrial metallurgical complex was also developed. This paper will present this work and the results achieved.
