This study aims to apply the cam clay model to predict the behavior and at the same time determine the shear strength parameters of some selected mine tailings in the Philippines namely Negros Oriental copper mine tailings, Cavite concrete aggregate mine tailings and Davao gold mine tailings. Tone of mine tailings are contained in dams which serve no purpose and could pose as threat if ever dam failures would occur and it is the interest of this paper to determine which among these three mine tailings possess strength parameters which may serve as construction materials. Three types of tiaxial tests, unconsolidated undrained test, consolidated undrained test and consolidated drained test, were conducted on the mine tailings in the determination of the shear strength parameters. The results of these tests classified Cavite concrete aggregate mine tailings as the mine tailing which has the greatest strength followed by the Davao gold mine tailings and lastly, the mine tailing which exhibited the least strength is the Negros copper mine tailings.
