Agrellite () is a rare triclinic inosilicate mineral with four-periodic single chains of silica tetrahedra.

Jurbanite is a sulfate mineral with the chemical formula AlSO4(OH)·5H2O. Its molecular weight is 230.13 g/mol. It crystallizes in the monoclinic system and is dimorphous with the orthorhombic mineral rostite. Jurbanite occurs as a secondary (post-mine) mineral in mines containing sulfide minerals.

Kankite is a mineral with the chemical formula Fe3+AsO4·3.5(H2O). Kankite is named for the locality that yielded first specimens Kaňk, Czech Republic. Kankite formation is associated with old (1200- to 1400-year-old) mine dumps. It is yellowish-green on fresh exposure, with a paler greenish yellow on exposure to air.
