Floatation separation of galena, sphalerite, and pyrrhotite by combined depressant CCSL
工程科学学报, 2017 The flotation separation of galena, sphalerite, and pyrrhotite was investigated with CCSL as a depressant. Flotation test results show that galena and sphalerite can float but pyrrhotite can barely float with CCSL as a depressant.

Conditions of metamorphism of the Outokumpu Cu - Co - Zn deposit from sphalerite geobarometry [PDF]
Bulletin of the Geological Society of Finland, 1998 Electron microprobe analysis was used to determine Zn and Fe in homogeneous samples of sphalerite in mutual contact with pyrrhotite and pyrite from the disseminated ore layer stratigraphically high in the Keretti orebody at Outokumpu, Finland.

Advanced Functional Materials, EarlyView.Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Competitive adsorption mechanism of organic depressant SDD with BX on copper-activated sphalerite
工程科学学报, 2018 The separation of Cu-Zn polymetallic sulfide by flotation has been a difficult and well-researched topic in the field of mineral processing. One of the important reasons why it is difficult to separate Cu and Zn is the presence of a large amount of ...

Two-Stage Oxidative Leaching of Low-Grade Copper–Zinc Sulfide Concentrate
Microorganisms, 2022 Bioleaching may be effectively used to extract nonferrous metals from sulfide ores and concentrates. At the same time, some minerals are refractory and their bioleaching rate is often comparatively low that does not allow the required metal extraction ...
