AI Technical Summary
In the existing technology, when recovering sulfide-oxidation mixed lead-zinc ore, it is difficult to recover oxide minerals. The conventional flotation process is complicated and costly, and fine oxide minerals are easily lost, resulting in poor recovery effect.
By using a combination of sodium fluorosilicate, sodium sulfide and sodium humate as inhibitors and combining them with reverse flotation technology, the synergistic effect of the combined inhibitors can achieve the simultaneous recovery of lead and zinc oxide minerals and simplify the process flow.
It improves the flotation level of lead-zinc oxide minerals and the comprehensive utilization rate of resources, reduces the recovery cost, simplifies the process flow, and enhances the adaptability to fluctuations in ore properties.
