“…In addition, hydration refines the pore structure and blocks the transport channels of Cr ions, facilitating solidification/stabilization [ 88 ]. Calcite, calcium silicate, calcium hydroxide, and calcium silicate may play a key role in immobilizing As species and heavy metals in PCCPB [ 89 ].…”

“…5B), which are characterized by the arising of a new band (1013 cm −1 ) attributable to ν3 vibration (antisymmetric stretching) of phosphate 58 , and the recession or disappearance of the nitrate band (1384 cm −1 ) as compared to the pristine ones. Note that a weak shoulder band at 1421 cm −1 assignable to ν3 vibration of carbonate 59 was also detected, suggesting that anion exchange between the intercalated nitrate and the carbonate from dissolved air is likely to occur along with P adsorption.…”

“…In addition, the utilization of mine tailings contributes to the occurrence of arable land due to the elimination of waste storages. In recent years, interest associated with the utilization of mine waste in geopolymers is rapidly growing [34][35][36][37][38][39][40][41][42][43][44][45][46]. So over the last decade interest in this problem has almost doubled.…”
