efficient and comprehensive recovery of valuable compo-
nents from the resource.
CONCLUSIONS
It is evident from the flotation test that the collector BK386
exhibits outstanding performance and synergizes effectively
with isobutyl xanthate (SIBX), thereby significantly enhanc-
ing Cu recovery in the bulk flotation process. The effects
of grinding fineness, rougher pH value, and reagent dos-
age were systematically evaluated while employing BK386
as the copper collector. Through closed-circuit testing, it
was determined that a bulk concentrate with a Cu grade
of 28.95%, Cu recovery of 90.33%, Mo grade of 0.15%,
and Mo recovery of 72.7% could be achieved. These results
underscore BK386s exceptional adaptability and the high
efficiency of the bulk flotation process.
