Raman spectroscopy of smithsonite [PDF]

open access: yesJournal of Raman Spectroscopy, 2007
AbstractRaman spectroscopy at both 298 and 77 K has been used to study a series of selected natural smithsonites from different origins. An intense sharp band at 1092 cm−1 is assigned to the CO32− symmetric stretching vibration. Impurities of hydrozincite are identified by a band around 1060 cm−1.

Research of kinetics of zinc leaching with sulfuric acid from smithsonite [PDF]

open access: yesMetalurgija, 2021
The study investigates the kinetics of zinc leaching from smithsonite with sulfuric acid in order to expand the zinc production feedstocks. The recovery rate of zinc from smithsonite into water-soluble zinc sulfate was found at different leaching time ...

DFT simulation of S-species interaction with smithsonite (0 0 1) surface: Effect of water molecule adsorption position

open access: yesResults in Physics, 2019
Surface sulfidization is the key to achieving good flotation performance of smithsonite, but its reaction mechanism at the atomic level remains poorly understood.

Origins of Colour of Smithsonite from Yunnan, China

open access: yesMinerals, 2023
Smithsonite exhibits an extensive range of colours in nature. The internal features, spectral characteristic, and trace elements of several coloured smithsonites (e.g., white, blue, blue-green, yellow, orange, and pink) from Lanping District, Yunnan Province, China, were analysed and the relationship between smithsonite colour and trace elements and/or

The Effect of Polystyrene on the Carrier Flotation of Fine Smithsonite [PDF]

open access: yesMinerals, 2017
Carrier flotation is a common technique used to improve flotation recovery of ultrafine ores. In this study, we used coarse polystyrene as the carrier material to enhance flotation recovery of fine smithsonite (ZnCO3) particles. Sodium oleate was used as the collector and played a role in the adhesion of fine smithsonite to polystyrene due to its ...
