Bismite is a secondary oxidation zone mineral which forms from primary bismuth minerals. It was first described from Goldfield, Nevada in 1868, and later from the Schneeberg District, Ore Mountains, Saxony, Germany.

铋华 （英語： Bismite）是 铋 的 氧化物 矿物 三氧化二铋 （Bi 2 O 3）天然存在的矿物。 矿物一般呈块状或粘土状，不形成宏观晶体。 颜色呈绿色至黄色。 它具有8.5至9.5的比重，在非天然金属矿物中是相当高的。 铋华是由初级铋矿物氧化形成的次级矿物。 该矿物于1868年首次在美国内华达 戈尔德菲尔德 发现，之后再德国萨克森的 厄尔士山脉 地区也发现了此矿物的存在。 ^ Warr, L.N. IMA–CNMNC approved mineral symbols. Mineralogical Magazine. 2021, 85 (3): 291–320. …

For Bismuth in its composition. NOTE: Numerous localities for bismuth oxides have been reported, but modern confirmation is required, as most have proven to be carbonates, etc. As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams.

是辉铋矿等含铋矿物氧化后的次生矿物。 用于提炼铋和制取氧化铋、硝酸铋、碱式硝酸铋等。 化学成分Bi2O3。 单 斜晶系。 通常呈土状、块状、被膜状。 麦 黄、微绿、浅灰等色。 玻璃光泽或土状光 泽。 硬度变化很大，致密块状者可达4.5， 土状者则降至1。 比重8.64～9.22。 见 于含铋矿床的氧化带，是辉铋矿、自然铋氧 化后所形成的次生矿物，因而有时可见到 呈辉铋矿柱状晶形的假像产出。 量多时可 作为铋矿石利用。 化学组成，铋华族矿物属A2X3型化合物。 人工合成 …

Tiny, bright yellow, scaly crystals of bismite on quartz. Purchased in 2021. The photo is far from perfect, but the only one showing crystals from this locality, and hence better than nothing in my opinion! An improved version will be taken, pending better equipment! © Andrew Hodgson

Bismite is a rare bismuth oxide. It is a mineral of high density (more than 8) which results from the oxidation of bismuth minerals in the superficial zone of high temperature veins. Its name derives from its chemical composition : bismuth. In collection samples, confusion with bismutite, bismuth carbonate, seems frequent. It forms earthy to ...

Bismite is a bismuth oxide mineral, bismuth trioxide or Bi2O3. It is a monoclinic mineral, but the typical form of occurrence is massive and clay-like with no macroscopic crystals. The color varies from green to yellow.
