Study on treatment of lead-zinc mineral dressing …
Lead-zinc ore is often processed using high alkali rapid flotation technology for ore dressing. The water quality characteristics of the ore dressing wastewater generated during the ore dressing process are complex, with high concentrations of COD, heavy metals, solid suspended solids, and salt, as well as large pH value fluctuations. The difficulty of wastewater treatment is high, …
