methodology involved feeding rejected material back into
the processing circuit and measuring the impact on copper
recovery. This approach provides a more rigorous test of the
BOS system than traditional methods, which typically rely
on static testing and do not evaluate system functionality
as a whole. The Kansanshi validation methodology should
represent a new standard for proof of BOS systems.
Overall, the Kansanshi BOS program is a success story
that demonstrates the potential of sensor-based BOS to
improve the efficiency and profitability of mining opera-
tions. The scale of the project, the effectiveness of the BOS
system, and the innovative validation methodology all
make the Kansanshi BOS program a significant step in the
development of sensor-based BOS technology.
