Investigation on a Novel Galena Depressant in the Flotation Separation from Molybdenite

Abstract

In this study, a novel organic depressant maleyl 5-amino-1,3,4-thiadiazole-2-thiol (MATT) was synthesized and utilized as a galena depressant in the flotation separation of molybdenite and galena. The results of the flotation test indicated that MATT exhibited an excellent depression ability on galena but barely influenced the flotation of molybdenite in the pH range of 6.0–11.0. Zeta potential results suggested that MATT preferentially adsorbed on galena surface. UV-visible spectroscopy analysis indicated that the stoichiometric ratio of lead ion and reagent in the complex compound. XPS analysis demonstrated that the S (-SH) atom and N (1,3,4-thiadiazole group) atom of MATT coordinated with the Pb atom on galena surface.

Construction of Thiadiazole‐Linked Covalent Organic Frameworks via Facile Linkage Conversion with Superior Photocatalytic Properties

“…In addition, the deconvoluted S 2 p XPS spectra of TDA‐COF present one binding energy peak at 164.6 eV, corresponding to thiadiazole S atom (Figure 2e ). [ 39 ] Therefore, the above evidences could well confirm the successful transformation of NAH‐COF into TDA‐COF.…”

Synthesis, Spectral Characteristics, and Molecular Docking Studies of 2,4-Dichloro-N-(2,2,2-trichloro-1-((5-(phenylamino)-1,3,4-thiadiazol-2-yl)amino)ethyl)benzamide

“…Derivatives of 1,3,4-thiadiazoles are widely used in coordination chemistry as ligands [42][43][44], in the synthesis of polymers [45], and the creation of polymer films [46,47]. The prospects of using 1,3,4-thiadiazoles in optoelectronics [48], in the purification of water from heavy metal ions [49], for the separation of minerals by the flotation method [50], and the creation of corrosion-resistant coatings [51] are discussed in the literature. A large number of works are devoted to the development of dyes and fluorescent markers based on 1,3,4-thiadiazoles [46,52,53].…”
