The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of the minerals and gangue requires a 65 mesh grind for liberation. The problem is to produce marketable grades of lead and zinc concentrates.
Consequently, the end products of ore or industrial mineral processing and coal washing are the same: (a) a concentrate of the sought-after commodity; and (b) a quantity of residue wastes known as tailings. Tailings typically are produced in the form of a particulate suspension, that is, a fine-grained sediment-water slurry.
An integrated hydrometallurgical process was used for the zinc leaching and purification from a zinc ore containing 9.75 wt% zinc.

Flotation machines play a pivotal role in lead-zinc ore processing by facilitating the separation of valuable minerals from gangue through the process of flotation.
Moreover, evaluating whether tailings processing steps like grinding, additional leaching, ore concentration (flotation), roasting, magnetic separation, or other metallurgical processes should precede or follow leaching is crucial.
A comprehensive recovery process was developed in this work to realize the separation and enrichment of copper, zinc, and iron minerals from a polymetallic ore, where the scavenger numbers of copper and zinc flotations and iron magnetic separation, respectively, were 2, 2 and 1, based on industry experience.
The tailings of lead-zinc oxide ore minerals are more complex, and the associated components are unstable. Therefore, the preferential flotation process is often selected as the main separation process, and desliming operations are performed before flotation to improve flotation indicators and reagent dosage.
