一、硫铁矿碴简介磷肥厂在生产硫酸的同时,排出红色粉粒状的硫铁矿碴,一般来说,每1.1吨硫铁矿在一千三百度高温炉内能提炼硫酸0.1吨,排出矿碴1吨左右。这种矿碴由于目前国内提炼水平所限,多数作为工业废碴处理,中型的磷肥厂每年都有万吨的废碴堆积(指具有制造硫酸生产线的工厂),既占用土地又污染空气。矿源不同,矿碴的组成成份也不同,就以扬州磷肥厂使用江苏省句容县团山、盘
First, the pyrite ballast Brief introduction Phosphate fertilizer plant in the production of sulfuric acid at the same time, discharge of red powder granular pyrite slag, in general, every 1.1 tons of pyrite in the 1300 Baosteel furnace can extract sulfuric acid 0.1 tons, discharge About 1 ton of ore ballast. Due to the current level of domestic refining, most of this ballast is treated as industrial waste ballast. Each year, medium-sized phosphate fertilizer plants accumulate 10,000 tons of waste ballast (referring to factories with a sulfuric acid production line) that occupy land and pollute the air. Different sources, the composition of mineral ballast is also different, on the use of Yangzhou phosphate fertilizer plant in Jurong County, Jiangsu Province Mission Hill, plate
