Tailings disposal: choosing the right technology. Mining operations generate much larger tailings volumes than mined volumes, and it is imperative that mine operators dispose of these tailings. This can be a complex process, especially given the hauling distance to reach the disposal sites in the tailings facility.

TAILINGS DISPOSAL SYSTEM AND FACILITIES. At closure, the DSTP pipeline will be flushed to remove residual tailing. Land - based infrastructure will then be removed, while the outfall pipeline will remain in situ.To comply with draft DSTP technical guidelines, post closure environmental monitoring must commence at the time of mine closure.
