Solution chemistry of anionic/nonionic surfactants and its role in flotation separation of quartz from feldspar

摘要

Collecting properties of nonionic surfactant(Triton X100) with sodium oleate for quartz and microclinewere studied using Hallimond tube, frothability tests,conductometric titration and ling phenomenon of Triton X100.The influence of Na-oleate on nonionic flotation of quartz andfeldspar was studied. The results suggested that at a smalldosage of Na-oleate, flotation of quartz was enhanced andmicrocline remained unfloated, whereas the pH flotation limitfor quartz was enlarged. At higher dosage of Na-oleate,microcline can be floated. The results are explained by themutual action of Triton X100 and oleate and the predominantrole of hemimicellization phenomenon.
