Numerous studies have addressed the role of ultrasonication on floatability minerals macroscopically. However, impact acoustic waves mineral hydrophobicity and its physicochemical aspects were entirely overlooked in literature. This paper mainly investigates ultrasonic power time wettability chalcopyrite, pyrite quartz. For this purpose, contact angle collectorless microflotation tests implemen...

A first-principles study of the birefringence and the frequency dependent second harmonic generation (SHG) coefficients of the ternary pnictide semiconductors with formula ABC2 (A = Zn, Cd; B = Si, Ge; C = As, P) with the chalcopyrite structures was carried out. It uses a recently developed computational approach based on the self-consistent linear muffin-tin orbital (LMTO) band-structure metho...

Copper content in copper smelter slag exceeds that ores, which has attracted increasing interest to recover from this by-product of pyrometallurgical production. The isopropanol-sulfuric acid-ozone system been tested under different conditions extract metal containing chalcopyrite as a mineral. Isopropanol solvent played key role the recovery 87% after 5 h leaching, while use an aqueous solutio...

In this study, chalcopyrite (CuFeS2), a natural mineral with bimetallic structure, was used as the activator to generate radicals for removing organic pollutants from aqueous solutions via activation of peroxymonosulfate (PMS). Sulfisoxazole (SIX), sulfonamide antibiotic, selected model pollutant. The results showed that highly reactive toward PMS; under conditions 50 µM PMS and 1 g/L chalcopyr...

Leptospirillum ferriphilum plays a major role in acidic, metal rich environments where it represents one of the most prevalent iron oxidizers. These milieus include acid rock and mine drainage as well as biomining operations. Despite its perceived importance, no complete genome sequence of this model species' type strain is available, limiting the possibilities to investigate the strategies and...

cuals2  chalcopyrite  nanocrystalline  are  synthesized  with  facile method.  the  heat  arrested  solvothermal  method  for  synthesize nanocrystalline  were  investigated.  the  time  duration  of  synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters  that we are  studied. the nanoparticles were  synthesized with cucl, alcl3 and  thiourea (sc(nh2)2) as ...
