Effect of Gangue Minerals on Pulp Rheology and Flotation Behavior of Smithsonite

open access: yes, 2022
The pulp rheology is an important factor affecting flotation performance. Gangue minerals have a significant impact on the rheological property of smithsonite (ZnCO3).

Sulfidation of Smithsonite via Microwave Roasting under Low-Temperature Conditions

open access: yes
This study employs microwave roasting to decompose smithsonite mineral (zinc carbonate) into zinc oxide, which then reacts with pyrite to sulfurize its surface, forming zinc sulfide.

XPS & FTIR study of adsorption characteristics using cationic and anionic collectors on smithsonite

open access: yes, 2006
The adsorption of cationic and anionic collectors on the surface of smithsonite was studied using diffuse reflectance FTIR (DRIFT) and X-ray photoelectron spectroscopy (XPS or ESCA) techniques.

A Mechanism for the Adsorption of 2-(Hexadecanoylamino)Acetic Acid by Smithsonite: Surface Spectroscopy and Microflotation Experiments

open access: yes, 2018
Zinc is mostly extracted from oxidized zinc and zinc sulfide minerals, and this process involves flotation as a key step. While it is easier to float the sulfide mineral, its consumption and depletion has led to an increased reliance on oxidized zinc ...
