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 ...

Leaching and thermal decomposition of mechanically activated sphalerite-pyrite mixture [PDF]
Acta Montanistica Slovaca, 1997 The effect of mechanical activation and pyrite addition on the thermal decomposition and acid leaching of sphalerite was studied. Mechanical activation enhances both hydrometallurgical and pyrometallurgical processing of sphalerite.

Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups
Advanced Materials Technologies, EarlyView.Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...

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.

Advanced Science, EarlyView.Inspired by the twin grain boundary discovered in natural gyroidal networks, a series of gyroid‐derived photonic crystals are constructed based on defect‐symmetry engineering. The new series of structures enables monotonic tuning of the width of the photonic bandgap (PBG) while the central frequency of the PBG maintains stable.
