Pyrrhotite Assignment Point
1 天前 Pyrrhotite is a common bronzecoloured magnetic mineral consisting of ferrous sulphide in hexagonal crystalline form It is also called magnetic pyrite, because the color is similar to 磁黄铁矿（pyrrhotite） 有不同的类型，分别属于六方或单斜晶系的硫化物矿物。 化学式中的值通常为0 1～0 2；如值为0，即与陨硫铁 (FeS)相同。 磁黄铁矿呈带红色色调的暗青 磁黄铁矿（pyrrhotite） 基础知识 化石网 When exposed to water and oxygen, the mineral’s expansion and decay leads to telltale spidery cracks and eventually can cause the concrete to crumble, thus the description Pyrrhotite in concrete causes crumbling foundations in MA مصنع كسارة 4060 طن كل ساعة من, قدرة 250 طن ساعة, الفك محطم بيع طن في الساعة 100 طن من, التلقائي بالكامل كسارة الفك الحجر في الهند 200 طن في الساعة, حتي الفك محطم 150 2250 للبيع الفك حجر محطم مع نوعية جيدة من التحقق من الشركة المصنعة كسارة الفك لوحة المواصفاتآلة تصنيع الرمل 5X يتم تصنيعها بواسطة لى مينغ للصناعات ا 4 11/26/2018 لى مينغ للصناعات الثقيلة 700 طن من خط إنتاج الجرانيت منتوجات جديدة يقدم كسارة ومطحنة لاستخراج المعادن، سحق، خلع الملابس لوحة مقاومة للتآكل الفك للكسارة الفكية
Pyrrhotite: The mineral pyrrhotite information and pictures
The variation of iron in Pyrrhotite's structure is also responsible for more than one crystal symmetry type, allowing it to form in both hexagonal and monoclinic symmetries Multiple crystal symmetries should technically classify Pyrrhotite as a mineral group rather than a single mineral, but a subclassification is rarely made due to polytypes appearing similar and perhaps even Pyrrhotite Formula Fe 7 S 8 Crystal System Monoclinic Crystal Habit Tabular, Platy, Massive Granular Cleavage Imperfect, Imperfect, None Luster Metallic Color bronze, bronze red, dark brown Streak gray black Class Monoclinic Prismatic Fracture Uneven Hardness 354 Data courtesy of WebmineralPyrrhotite Mineral Specimen For SaleForms thin to thick tabular crystals, also bipyramidal to prismatic or barrel like crystals Most pyrrhotite is massive The Sudbury ores formed from sulfide rich magmas Trepca crystals to 10cm Scale at bottom of image is an inch Scale at bottom of image is an inch El Potosi mine in crystals to 15cmPyrrhotite Pyrrhotite For the species, this is a large crystal, with the largest crystal measuring 5cm The smaller crystal is 3cm This and many more mineral specimens are available for sale at Dakota Matrix MineralsPyrrhotite Mineral Specimen For Sale The problem with pyrrhotite Posted by John on 4th September 2017 Lori Kormos, Principal GeoScientist at XPS asks “do your ores contain pyrrhotite?
