Inspired by recent theoretical predictions on band convergence in the tetragonal chalcopyrite compounds, we have explored the influence of the crystal structure on the transport and bandstructure of different quaternary chalcopyrites. In theory, a changing lattice parameter ratio of c/2a towards unity should lead to band convergence due to a more cubic and higher symmetry structure. In accordan...

Abstract The Herberton Mineral Field in Northeast Australia hosts world class magmatic-hydrothermal Sn–W polymetallic deposits that are enriched In. Baal Gammon and Isabel from the contains early tin, as cassiterite, overprinted by sulfide mineralization chalcopyrite, sphalerite, galena, pyrrhotite, stannite. We investigated distribution of In ores these two deposits, calculated temperature for...

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...
