Solar RRL, Volume 10, Issue 18, 28 September 2026.This work presents the development of n‐type Zn1−xGexOx+1 using radiofrequency magnetron sputtering to suppress interface recombination at the heterojunction of Cu(In,Ga)S2 (CIGS) solar cells. The solar cell device with the Zn1−xGexOx+1 buffer layer directly deposited on CIGS absorbers demonstrates a conversion efficiency comparable to that of a device

Effect of Ultrasonic Pre-Treatment and Aeration on Flotation Separation of Chalcopyrite from Pyrite [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2018 In this paper, the effect of ultrasonic pre-treatment and aeration on the flotation separation of chalcopyrite from pyrite was investigated at different amounts of potassium ethyl xanthate (KEX), as a collector, and pH values.

Geological Journal, Volume 61, Issue 9, Page 2940-2957, September 2026.Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Effect of redox potential on chalcopyrite dissolution imposed by addition of ferrous ions
Eclética Química, 2018 Copper is a metal with a great economic interest and about 70% is found in nature in chalcopyrite form (CuFeS2). However the chalcopyrite dissolution is a challenge for industries as well as researchers because of its slow dissolution kinetics.

The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1962 Thermal transformation of chalcopyrite in argon atmosphere has been studied in temperature from 200°up to 1000°C, using the thermogravimetric, X-ray analyes and erflected microscopic examination. Both of the thermogravimetric and differential thermal analyses curves suggest some endouthermic eraction or transformation, as formerly recognized, at 540 ...

Leaching of a Mongolian chalcopyrite concentrate
Mongolian Journal of Chemistry, 2018 A Mongolian chalcopyrite flotation concentrate was leached using sodium hypochlorite adjusted to different pH using hydrochloric acid. It was found that using a starting pH of below 5.0 resulted in more efficient leaching.
