Itabirite iron ore mines produce concentrates, which form the main source of revenue for their mining operation. In order to generate the desired levels of quantity and quality of concentrate that are required to maximize the DCF (Discounted Cash Flow) of the project, these mines seek the optimization of the blocks to be mined.

In the literature, African iron ore types are graded as low-grade (60.0-62.9% Fe; 8.612.5% SiO 2 and insolubles), high-grade (66.069.9% Fe; 0.8-4.5% SiO 2 and insolubles), and meduim-grade as the remaining portion (Astrup et al., 1998). The low-grade ore used in this work contains less than 60% Fe.
