红石膏胶结充填技术

Cemented Filling Technology of Gypsum Rubrum

红石膏是钛白粉生产的废料,每生产1t钛白粉排放5t石膏,地表堆放严重污染环境。利用红石膏的活性,通过添加激发剂,获得满足矿山充填要求的红石膏胶凝剂。珊瑚矿红石膏全尾砂胶结充填实践表明,该技术不仅将红石膏废料加以利用,而且充填胶凝剂成本下降50%以上,为大量利用红石膏开辟了一条低成本高收益的途径。

While producing 1ton of titanium dioxide,five tons of gypsum rubrum would discharged as the waste and be stacked up on the surface to pollute the environment seriously.With the activity of gypsum rubrum,the gypsum rubrum gelling agent which met filling requirement was acquired by adding exciting agent.The practice of gypsum rubrum cemented filling with unclassified tailings in Shanhu mine showed that in this technology,not only the waste of gypsum rubrum was utilized,but also the filling cost reduced by more than 50%.The study provided a low cost and high profit way to utilize the gypsum rubrum in a large quantity.
