2021.7.1 1. Introduction. Crushing and grinding are necessary for the processing of minerals that coexist closely with gangue minerals (Gong et al., 2020, Wills and Finch, 2016).Crushing-grinding provides the materials with a suitable particle size and the sufficient liberation of useful minerals for the subsequent separation process (Li and

To finish the flotation process, the discharge from the second flotation step is dewatered again, and a cationic amine is used for collection as the feldspar is floated away from quartz in an environment of hydrofluoric acid (pH of 2.5 to 3.0). If feldspathic sand is the raw material, no size reduction may be required.
