Origin of colour zoning in cassiterites from tin deposits within the Bushveld Complex, South Africa [PDF]

Bulletin of the Geological Society of Finland, 1986
Cassiterites with striking colour zones from the syngenetic tin deposits at Zaaiplaats and from the epigenetic tin deposits at Rooiberg, Leeuwpoort and Union Mines, in the Central Transvaal, have been analysed by microprobe.

A Common Reference Material for Mass‐Dependent Sn Isotope Compositions: An Inter‐Laboratory Calibration Approach

Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 341-367, June 2026.
Key Points We recommend using the notation δ122/118SnNIST SRM 3161a for mass‐dependent Sn isotope data. We derived conversion factors relative to NIST SRM 3161a for Puri Sn CEZA (0.132 ± 0.011‰), Sn Lyon (0.229 ± 0.016‰), Sn IPGP (0.162 ± 0.018‰). Tin isotope compositions are presented for SPEX CertiPrep Sn and nine USGS reference materials.

Flotation Recovery of Fine Slime Cassiterite from Gravity Tailings

Kuangchan zonghe liyong
The concentrator of Dachang mining area in Guangxi adopts the method of shaking table gravity separation to recover cassiterite in production, which has problems such as difficult cassiterite separation and large loss of fine mud.

Tin-bearing magnetite with nanoscale Mg-Si defects: Evidence for the early stages of mineralization in a skarn system

Frontiers in Earth Science, 2023
Tin-bearing magnetite is reported from several types of magmatic-hydrothermal ore deposits. The question of whether tin is incorporated within solid solution, as Sn4+, or as nanoinclusions remains open, however.

Mineralogical characterization of Sn deposits from the Santa Fe District, Bolivia [PDF]

, 2015
The Sn-Zn-Pb-Ag Japo-Santa Fe-Morococala ore deposit is located in the Central Andean Belt province. The ore mineralization is hosted in a Paleozoic metasedimentary sequence and porphyritic Oligocene-Miocene igneous rocks. Ore minerals occur in veins and

Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media

Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

Experimental and Thermodynamic Modeling Study of Phase Equilibria in the FeO–Fe2O3–SnO–SnO2–SiO2 System

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Experimental investigation and thermodynamic modeling of the phase equilibria in the FeO–Fe2O3–SnO–SnO2–SiO2 system have been undertaken to characterize Sn behavior in iron silicate slags for recycling of waste electrical and electronic materials (WEEE) through black copper process.
