improvements were achieved in elemental composi-
tion, breakage behavior, and recoveries for zinc and lead.
Integrating a pre-concentration stage using SBS showed
promise in enhancing SAG and ball mill throughput while
simultaneously decreasing energy and water usage and min-
imizing fines production, emphasizing its role in optimiz-
ing operational efficiency.
The second case focused on an oxidized copper ore,
highlighting substantial reductions in acid consumption
across multiple stages of the pre-concentration process. The
effective targeting and removal of carbonate-rich fractions
early in the processing chain underscored the efficiency of
SBS in improving both total and soluble copper grades and
reducing acid consumption.
Furthermore, it is presented a comparative study for
chromite, showcasing the superior performance of SBS
over traditional pneumatic jigging in terms of chromite
concentrate quality, metallurgical recovery, and environ-
mental sustainability. SBS not only achieved higher Cr₂O₃
grades and better recovery rates, but also minimized water
usage, positioning it as a more effective and sustainable
alternative.
These studies collectively underscore the transformative
potential of SBS technology in mineral processing, offer-
ing significant benefits in terms of operational efficiency,
resource conservation, and environmental stewardship.
By reducing water and energy consumption, optimizing
mineral recovery, and minimizing environmental impact,
SBS represents a strategic pathway towards achieving ESG
objectives and fostering sustainable mining practices in
alignment with global sustainability goals.
