DOI: 10.1080/01496395.2016.1260590
Abstract: ABSTRACT Flotation separation of scheelite from calcite is difficult because of the existence of the same cation in the minerals and similar physicochemical characteristics. Many studies have been performed to determine the selective depressants for… read more here.

DOI: 10.3390/ma15134699
Abstract: The flotation separation (FS) of both scheelite and calcite minerals with similar physicochemical properties remains challenging, since the Ca active sites exist on their surfaces. The present work investigated the effects of different addition points… read more here.
