kanema

Wulfenite ndiwotsogolera molybdate mineral ndi PbMoO4. Nthawi zambiri imapezeka ngati makina opangidwa ndi makina amphamvu kwambiri a lalanje, wofiira ndi wachikasu, nthawi zina bulauni, ngakhale kuti mtunduwo ukhoza kusinthasintha. Mu mawonekedwe ake achikasu nthawi zina amatchedwa "yellow lead ore".

Zimaphatikizapo mu njira ya tetragonal, yomwe nthawi zambiri imachitika ngati phokoso, piramidi kapena makatani. Amakhalanso ngati mabala a dziko lapansi. Amapezeka m'madera ambiri, okhudzana ndi otsogolera monga mchere wachiwiri wokhudzana ndi malo okhotakhotakhota. Ndilo gawo lachiwiri la molybdenum, ndipo likufunidwa ndi osonkhanitsa.
