Interactions between sulphide minerals and alkylxanthates 8. A vibration and X-ray photoelectron spectroscopic study of the interaction between chalcopyrite, marcasite, pentlandite, pyrrhotite and troilite, and ethylxanthate and decylxanthate ions in aqueous solution

Infrared Evaluation of Composition and Structure of Ethyl Xanthate Monolayers Produced on Chalcopyrite, Tetrahedrite, Tennantite at Controlled Potentials

“…1e, f ). The iron xanthate complex is not formed on ''fresh'' chalcopyrite surface be-deduced from the recorded DRIFT spectra (28) which is in agreement with the recently reported results (1,2). cause cuprous xanthate is the more stable product.…”

“…It can be speculated that the preparation of the finely about the spectral feature details. The determination of moground sample of chalcopyrite for DRIFT measurement lecular orientation quantitatively requires a good quality (drying) is the reason for a failure (28) to observe the ethyl spectra at various polarization and incidence angles. Because dixanthogen formation.…”

In SituInfrared Characterization of Surface Products of Interaction of an Aqueous Xanthate Solution with Chalcopyrite, Tetrahedrite, and Tennantite

“…One part of the sediment with a significant amount of collector solution was contacted with the reflection element and investigated in situ by ATR technique. The second part few published works on the determination of the adsorption was centrifuged, dried at room temperature, and studied ex products of xanthate on chalcopyrite (1)(2)(3)(4)(5), and they present situ by DRIFT technique. Adsorption of xanthate was perdifferent conclusions about the surface composition and the formed from basic (pH 9.5 { 0.2) and acidic (pH 5.5 { 0.2) mechanism of adsorption.…”

Surface Spectroscopic Studies of Factors Influencing Xanthate Adsorption on Coal Pyrite Surfaces†

“…4,6 In those studies the mineral pyrite was treated with an Fe3`complexing agent in order to remove all Fe oxidation products from the pyrite surface. Subsequent treatment with xanthate solution yielded minimal adsorption of the xanthate.…”
