摘要

Characteristically, jarosite waste released from zinc metal extraction process is hazardous in nature and worldwide disposal has become a major concern to safeguard the environment and ecology. In the present study, a process was developed for immobilisation and recycling jarosite waste generated by zinc industry by developing non hazardous building material using other inorganic industrial wastes as additives. Detoxification of jarosite waste was achieved through immobilization by making composite products using coal combustion residues (CCRs), pond coal combustion residues (PCCRs) as well as marble processing residues (MPRs) as additives alongwith clay using solidification / stabilisation (S/S) and sintering processes.
