Yao, Xiang published the artcilePreparation of cinnamon hydroxamic acid and its flotation characteristics and mechanism to fine-grained wolframite, Name: Methyl 3-phenyl-2-propenoate, the publication is Journal of Molecular Liquids (2022), 119721, database is CAplus.
A new collector-cinnamon hydroxamic acid (CIHA)-was synthesized from Me cinnamate using the hydroxyamine method. The results of single-mineral flotation and artificially mixed-mineral flotation indicated that CIHA had good collection performance and selectivity. Adsorption-capacity test results indicated that the CIHA collector adsorbed wolframite and quartz, and the adsorption intensity of wolframite was higher than that of quartz. The adsorption mechanism was investigated via zeta-potential anal., Fourier transform IR spectroscopy, and XPS. The results indicated that CIHA interacted with Mn on the wolframite surface via Pb2+ activation to form a surface Mn-O-Pb2+ complex, which formed a new Fe-O bond with Fe. Hydroxamic acid may have formed a five-element chelated hydroxamic group with the metal on the wolframite surface. The hydrophobicity of the wolframite surface was improved, making the wolframite more easily attach to bubbles and be more easily carried to the pulp surface.
