Mineral Many sulfide minerals are economically important as metal ores; examples include sphalerite (ZnS), an ore of zinc, galena (PbS), an ore of lead, cinnabar (HgS), an ore of mercury, and molybdenite (MoS, an ore of molybdenum. Pyrite (FeS), is the most commonly occurring sulfide, and can be found in most geological environments. It is not, however, an ore of iron, but can be instead oxidized to produce sulfuric acid. Related to the sulfides are the rare sulfosalts, in which a metallic element is bonded to sulfur and a semimetal such as antimony, arsenic, or bismuth. Like the sulfides, sulfosalts are
Khanozai making stainless steel. The Chromite Ore extracted in mountains of Khanozai and Muslim Bagh region consists 44.7 to 59.1 % of the Chromium. (Bilgrami, 1969). From Islamic Jurisprudence point of view, those extracted metallic minerals which are melted by fire in order to use them are subjected to Khumas (One-fifth or 20 %)- a type of Zakat, therefore, Chromite as a metallic mineral does fall in this category for which Khumas is necessary to be paid to the people mentioned in the Quran and hadith of Muhammad (Sahih Al Bukhari).
