XXXI International Mineral Processing Congress 2024 Proceedings/Washington, DC/Sep 29–Oct 3 507
CONCLUSION
STET has developed a robust industrial-scale process to
beneficiate iron ore based on tribo-electrostatic particle
charging and separation. These developments in process-
ing relatively fine iron ore help alleviate issues that arise
from this class of material, primarily tailings generation
or waste. Results from pilot-scale testing of two samples –
“ultrafines” and “air-classified” iron ore are presented in this
paper demonstrating successful enrichment of the products’
iron content. Different processing schemes were developed
to achieve a wide range of product grades to suit a variety of
different applications. The STET tribo-electrostatic separa-
tion is completely dry and it requires no water or chemical
agents, distinguishing itself from typical industry methods
like magnetic separation and flotation.
