Description:   The design of the tailings management system at Philex mill was described. Tails were cycloned with the coarse fraction sent to construct tailings dams and the fines (or slimes) sent for decantation and impoundment. Heavy precipitation, such as a typhoon, caused problems with the system. The dams would overflow as a result, and then threaten contamination of the surrounding environment. Drainage and diversion tunnels were added to accomodate the excess water, but were not effective. It was recommended that regulations on tailings dam design be changed to allow for a more suitable design.
