The Flotation Separation Mechanism of Smithsonite from Calcite and Dolomite with Combined Collectors
, 2023 Smithsonite, dolomite, and calcite are carbonate minerals. The crystal structures and spatial distribution characteristics of their common surface metal sites are similar, leading to difficulty in the flotation separation of smithsonite from these ...

Effects of physical and physico-chemical factors on pulp rheology of smithsonite [PDF]
, 2023 Pulp rheology is an important factor affecting flotation. The effects of particle size (150-74 μm, 74-38 μm, 38-23 μm, -23 μm), pulp density (11.76%-34.78%), pH (5.3-12.4), collector concentration (25-500 mg/dm3), and stirring intensity (400-900 rpm) on ...

Dynamic and Controlled Rate Thermal analysis of hydrozincite and smithsonite [PDF]
, 2008 The understanding of the thermal stability of zinc carbonates and the relative stability of hydrous carbonates including hydrozincite and hydromagnesite is extremely important to the sequestration process for the removal of atmospheric CO2. The hydration-

Flotation Separation of Smithsonite from Calcite Using Cupferron as a Collector
, 2023 The flotation separation of smithsonite and calcite is difficult due to their similar surface properties. In this study, cupferron was applied as a collector to realize the separation of smithsonite and calcite.

Medicine for the Material World
Archaeometry, Volume 68, Issue 3, Page 434-439, June 2026.ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

Leaching of zinc from calcined smithsonite using sodium hydroxide
, 2013 The processes of calcination and alkaline leaching were applied to treat a zinc oxide ore, smithsonite (ZnCO3). The phase evolution in the calcination was studied, as well as the effect factors on the leaching rate of Zn, such as calcination temperature,

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract NASA's Curiosity rover is exploring a 5 km tall sedimentary mound that is hypothesized to record the transition from a warm and wet (phyllosilicate‐rich) to a cold and drier (sulfate‐rich) Mars. Evidence of magnesium sulfate‐bearing rock has shown that Curiosity has crossed through this phyllosilicate‐sulfate transition.
