采用回转窑高温氯化焙烧工艺处理黄铁矿烧渣,回收有价金属并生产铁矿球团,在国外早已应用于工业生产。近年来日本已向一些国家出售此项专利。众所周知,回转窑氯化焙烧工艺生产铁矿球团,必须保证在不产生严重“窑结”的情况下,达到挥发脱除有价金属,和产出杂质含量及强度都能满足炼铁要求的球团之双
High-temperature rotary kiln roasting process using pyrite cinder, metal recovery and production of iron ore pellet, has long been used in foreign industrial production. Japan has sold the patent to some countries in recent years. As we all know, rotary kiln chloride roasting process to produce iron ore pellets, we must ensure that in the absence of a serious “kiln knot” to achieve volatile removal of valuable metals, and the output of impurities and strength can meet the requirements of ironmaking Double the ball
