 — Collector type and pulp pH play an important role in the lead–zinc ore flotation process. In the current study, the effect of pulp pH and the collector type parameters on …

 — As in most lead-zinc flotation operations, lead is separated first, followed by the zinc flotation stage. Due to the nature of the ore, lead minerals are frequently released from their gangue in coarse sizes, while zinc minerals need comparatively more grinding to produce the appropriate degree of liberation from accompanying gangue minerals.

 — The sulfidization-amine flotation method is commonly used for the beneficiation of zinc oxide ores. Lanping zinc oxide ores contains 8.40% zinc, with the main mineral being smithsonite; additionally, they have a high mud content. Conventional sulfidization–ammonium flotation presents a low flotation index and unsatisfactory …

 — In this study, a new flotation approach, a low-alkaline and non-desliming process, was introduced for improving lead and zinc recoveries, lowering production cost and reducing environmental pollution.Lab-scale experiments results show that the new process contributed to the flotation of the complex mixed sulfide-oxide lead and zinc ore …
