Effects of coarse chalcopyrite on flotation behavior of fine chalcopyrite

Minerals Engineering, 2021
Abstract The flotation of ultrafine particles is marked with low recovery due to low collision efficiency between particles and bubbles. Carrier-flotation is a method to enhance the recovery by the attachment of fine particles onto larger carrier particles. In this study, the effects of coarse chalcopyrite particles as a carrier on flotation behavior

Chalcopyrite/defect chalcopyrite heterojunctions on the basis of CuInSe2

Journal of Applied Physics, 1993
A new model for the formation of heterojunctions in polycrystalline CuInSe2 thin films on the basis of surface analysis experiments is presented. In situ photoemission measurements of CuInSe2 clearly show the existence of an In-rich n-type surface layer on samples relevant for solar-cell devices.

Electrochemistry of chalcopyrite

Hydrometallurgy, 1996
Abstract The electrochemical response of a massive chalcopyrite electrode at two different temperatures, 25°C and 68°C, were compared. The electrolyte used in the experiments was an acidic medium (0.4 g ·1 −1 (NH 4 ) 2 SO 4 , 0.5 g ·1 −1 MgSO 4 · 7H 2 O, 0.2 g ·1 −1 K 2 HPO 4 at pH = 2) which is suitable for the growth of the microorganisms ...

Competitive bioleaching of pyrite and chalcopyrite

Hydrometallurgy, 2006
Abstract An experimental study was conducted to investigate the heap bioleaching of a copper-gold concentrate using the Geocoat™ technique. Small-scale columns were operated at selected temperatures using bacterial consortia suited to these temperatures. In all experiments secondary copper sulfides would leach more rapidly than pyrite.
