arsenopyrite การใช้

• Gold-containing arsenopyrite ores are similarly reactive toward inorganic cyanide.
• Glaucodot is classed as a sulfide in the arsenopyrite l鰈lingite group.
• Arsenopyrite also can be associated with significant amounts of gold.
• When arsenopyrite is heated, it becomes magnetic and gives off toxic fumes.
• It forms a series with arsenopyrite ( FeAsS ).
• Its common associates include limonite, gypsum, scorodite, quartz and arsenopyrite.
• Associated minerals include arsenopyrite, stannoidite, chalcopyrite, chalcocite, sphalerite and tennantite.
• Arsenopyrite has a related structure with heteroatomic As-S pairs rather than homoatomic ones.
• Wall rocks generally contain more sulphides than the veins, in the form of arsenopyrite selvedges.
• On roasting arsenopyrite in air, arsenic sublimes as arsenic ( III ) oxide leaving iron oxides,
• It occurs associated with cassiterite, arsenopyrite, molybdenite, tourmaline, topaz, rhodochrosite and fluorite.
• Arsenopyrite isn't soluble in water, so it precipitates out and remains trapped in the filter.
• With 46 % arsenic content, arsenopyrite, along with orpiment, is a principal ore of arsenic.
• The veins commonly contain tourmaline, topaz, fluorite, apatite, wolframite, molybdenite, and arsenopyrite.
• It is a mineral of secondary origin, a result of the oxidation of copper ores and arsenopyrite.
• They are formed from alteration of arsenopyrite, and are found in the weathered zone of the deposit.
• Associated minerals include cassiterite, scheelite, bismuth, quartz, pyrite, galena, sphalerite, and arsenopyrite.
• These deposits are characterized by invisible ( typically microscopic and / or dissolved ) gold in pyrite and arsenopyrite.
• Highly anomalous values in gold are also known to occur locally within large arsenopyrites porphyroblasts in the host sediments.
• Arsenopyrite in older literature may be referred to as " mispickel ", a name of German origin.
