1562 XXXI International Mineral Processing Congress 2024 Proceedings/Washington, DC/Sep 29–Oct 3
RESULTS AND DISCUSSION
This section explores the outcomes and discussions stem-
ming from the Geometallurgy Program at the Vargem
Grande Iron Ore Complex, aiming to understand how the
program enhances mineral processing and overall plant
efficiency.
Characterization and Bench Scale Tests
The average Fe, SiO2, and major contaminant contents in
the desliming process feed are outlined in Table 1 for the
HZT samples and Table 2 for the ABO samples. The Fe
grade shows comparable values between the two deposits,
considering both IC (39.20% and 37.84%) and IF samples
