主要用途:提取硫的主要矿石原料。硫主要用于制取硫酸。硫酸主要用于生产化肥(如硫酸铵);硫酸在有机化工生产中用于酸化、磺化、催化;在冶金工业中用于钢铁、镍等金属酸洗、有色金属冶炼。
采集地点:内蒙古乌拉特后旗炭窑口硫铁矿区
Name:Pyrite Ore
Mineralogy:Ore minerals dominated by pyrrhotite and pyrite, with minor sphalerite, galena, chalcopyrite and magnetite. Gangue minerals include mostly dolomite, with subordinate quartz, calcite, sericite, chlorite and carbonaceous matters.
Genesis:Exhalite
Age:Mesoproterozoic
Usage:Extracting sulfur. Sulfur is mainly used for making sulfur acid, which is mainly used in fertilizer. In organic chemical industry sulfur is used for acidification, sulfatation, and catalysis. In metallurgy sulfur acid is used in scouring for steel and iron and nikel.
Sample site:Tanjiaokou pyrite mine, Wulatehouqi, Inner Mongolia.
