Utilizing in situ oxygen isotope analysis, we demonstrate the potential of cassiterite as a robust recorder of fluid source and evolution. Cassiterite is an ore mineral, and its mineral–water oxygen isotope fractionation factor is only weakly temperature-dependent. Unlike most explored gangue minerals such as quartz, cassiterite can provide a direct …

The separation and extration of tin and tungsten from wolframite – scheelite mixed ore with high tin content is urgently needed given the increasingly exhaustion of the high-grade tungsten ore. However, current tungsten hydrometallurgy technologies suffer from considerably drawbacks, such as low recovery of tin, high …

Tin-tungsten ore system, Pilok, Thailand 55 The presence of alkali feldspar in veinlets and the stability of a pale brown (not further identified) biotite phase in hydrothermally altered rock suggest local con- ditions of potassic alteration. The very minor abundance of hydrothermal biotite may be a consequence of a leucocratic, boron-rich ...
