The beneficiation of lithium minerals from hard rock ores: A
Jan 15, 2019 · It is important to note that the flotation of spodumene with oleic acid shows only a primary peak at pH 8, thus confirming the conclusion by Moon and Fuerstenau (2003) that the secondary peak at pH 4 was as a result of the interaction of oleate ion with iron impurity in the mineral (Menendez et al., 2004, Yu et al., 2015b).
