While the co-disposal method has been extensively explored for various mineral substances, a notable gap exists in the literature concerning its application specifically to tailings and waste rock generated from phosphate mining operations. This study aims to identify the optimal ratio for a mining tailings and waste rock mixture and evaluate its mechanical behavior in comparison to individual materials. Geotechnical characterization provided essential data for evaluating the applicability of the co-disposal technique. The mechanical behavior was evaluated with direct shear tests, revealing the substantial influence of waste rock on the mechanical properties of the mixtures. Notably, apparent cohesion in unsaturated conditions demonstrates the suction effect on shear strength in these materials. This comprehensive study contributes valuable insights into optimizing co-disposal practices for phosphate ore mining waste, addressing crucial aspects of safety and mechanical behavior in tailings and waste rock mixtures.
