TL;DR: In this article, the effect of Fe3+ ions as an activator on the flotation performance of cassiterite using benzohydroxamic acid (BHA) as the collector was investigated by the micro-flotation tests.
Journal ArticleDOI
Investigations on flotation separation of scheelite from calcite by using a novel depressant: Sodium phytate
TL;DR: In this article, the results of zeta potential measurements and FTIR spectra analysis demonstrated that sodium phytate adsorbed on the calcite surface and hindered the subsequent chemisorption of sodium oleate.

Activation role of lead ions in benzohydroxamic acid flotation of oxide minerals: New perspective and new practice.
TL;DR: A new hypothetic activation model was proposed to explain the improved performance of soluble lead-BHA complex and the proposed model was verified by the flotation experiment and adsorption test results and can help enrich the activation theory of metal ions in anionic collector flotation of minerals.

Adsorption of Pb(II)/benzohydroxamic acid collector complexes for ilmenite flotation
TL;DR: In this paper, the performance of separately added Pb2+ ions and benzohydroxamic acid (BHA) was compared with that of Pb 2+/BHA (Pb-BHA), and the possible adsorption mechanism on the ilmenite surface was investigated by conducting single-mineral flotation tests as well as zeta potential, ultraviolet (UV) spectroscopy, microcalorimetry, Fourier transform infrared spectrograph (FTIR), and X-ray photoelectron spectroscopic analyses.

Zeta potential of artificial and natural calcite in aqueous solution.
TL;DR: Previous measurements of zeta potential on natural and artificial calcite and carbonate are reviewed, a consistent linear relationship between equilibrium pH and equilibrium pCa or pMg irrespective of sample used or solution ionic strength is presented, and apparently identical natural carbonates display differing zeta Potential behaviour.

Activation mechanism of lead ions in cassiterite flotation with salicylhydroxamic acid as collector
TL;DR: In this paper, the effect of lead ions on cassiterite flotation with salicylhydroxamic acid as collector was assessed by a combination of microflotation tests, adsorption experiments, zeta-potential determinations, and X-ray photoelectron spectroscopy (XPS) analysis.

Selective flotation of scheelite from calcite: A novel reagent scheme
TL;DR: In this paper, octyl hydroxamic acid (HXMA-8) was used as an associate collector with NaOl in scheelite flotation, and the flotation tests showed that a novel reagent scheme, i.e., a lower dosage of SS (300 mg/L) and mixed collectors of HXMA+NaOl (total concentration 4.5 ǫ −10 −4 Âmol/L, preferred mass ratio of 1:2).
