Surface modification of smithsonite with ammonia to enhance the formation of sulfidization products and its response to flotation
TL;DR: In this article, a promising method of improving the sulfidization flotation of smithsonite through surface modification with ammonia was proposed, which increased the amount of sulfide ion species adsorbed onto the mineral surface, thereby facilitating the attachment of xanthate species onto the sulfified mineral surface and promoting its hydrophobicity.
Journal ArticleDOI
DFT insights into the electronic properties and adsorption mechanism of HS− on smithsonite (1 0 1) surface
TL;DR: In this paper, density functional theory calculations are conducted to investigate the electronic properties and adsorption mechanism of sulfide ion species on smithsonite (1.0.1) surface.
