New Minerals Discovered in Recent European Journal of Mineralogy Issues
The latest issue of the European Journal of Mineralogy reports two new mineral species—Belmonteite from Italy and Fengruiite from China—and a study on how Fe–Ti oxide textures affect vanadium extraction.
The recent volume of the European Journal of Mineralogy contains three stories published in 2026.
Story 2 describes Belmonteite (CaMn₂(AsO₄)₂(H₂O)₅·2H₂O), a new arsenate mineral found in Mn ore deposits of Graveglia Valley, eastern Liguria, Italy. Its crystal structure consists of {010} layers of six‑fold coordinated Mn atoms decorated with AsO₄ groups and Ca atoms connected through hydrogen bonds. The name honors Donato Bélmonté for his work on Ligurian mineralogy.1
Story 3 reports Fengruiite, a new Ag–Sb–Te sulfosalt discovered at the Haopinggou Ag–Pb–Zn–Au deposit in eastern Qinling, China. The mineral has a unique tellurium‑rich structure that helped trap silver during hot fluid formation, offering clues to how silver‑rich deposits form.1
Story 1 examines how exsolution textures in Fe–Ti oxide minerals influence crushing strategies and vanadium/titanium pre‑concentration. Some textures tightly intergrow minerals and hinder separation, while others form coarser structures that improve processing by magnetic and flotation methods; identifying these textures is essential for optimizing ore processing and resource use.1
