Flotation of gold and gold-bearing ores
ResultResearch investigations have until recently typically focused on the individual flotation behaviour of each gold-bearing mineral in synthetic mixtures and not on mixtures of sulfide minerals in 'real' ores ( Teague et al., 1999a ). In the flotation process, the main chemical effects are reagent type and pulp pH.

Flotation | SpringerLink
ResultFlotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.

Lead Zinc Sulfide Separation by Sequential Flotation
ResultThe Unit Flotation Cell will efficiently handle minus ¼" ball mill discharge and recover much of the lead as soon as it is free and reduced to flotation size. Often up to 70-80% of the lead can be recovered at this point in a high grade product which filters rapidly and is generally very low in zinc content.
