Phosphogypsum pretreatment with CaCO3 to improve the backfill performance
When acid phosphogypsum (APG) is recycled as aggregate of cemented backfill in mines, pretreatment is usually needed to reduce its adverse impact on the backfill. In this study, a new approach of using a neutral salt (CaCO3) to pretreat APG has been proposed to enhance the strength development of th...
