It often occurs as elongated prismatic crystals or in dense aggregates. Wolframite is a significant source of tungsten and is commonly mined alongside other minerals, including cassiterite (tin ore). Its tungsten content makes it an important ore for the production of tungsten metal and tungsten alloys.

The chemistry of hydrothermal tin(-tungsten) ore deposition
Several geologically likely deposition mechanisms have been tested, which differ in efficiency regarding the maximum tin ore grade that can be achieved in aluminosilicate host rocks. By contrast, wolframite can be precipitated by cooling of an Fe-W-bearing fluid without wall-rock reaction.Single-step acid neutralization of magmatic …

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 …
