Amaratunga and Hmidi (1997) investigated the use of gypsum β-hemihydrates (the most economical form of calcined gypsum) and PC in cold bonded agglomeration of fine gold mill tailings. It was concluded that a strength of 237 N/pellet can be achieved in the cold bonded agglomeration process by adding 4% binder (20% β-hemihydrate and 80% PC).
