Cobriza Mine

Cobriza Tailings Thickener Rehabilitation Study

Prior to joining Tierra Group, our Team investigated the failure mode for a 10-m diameter conventional tailings thickener and determining the feasibility of rehabilitating it. Activities included on-site forensic investigations and site surveying. A failure mode analysis determined unsuitable foundation preparation led to the thickener settling. Ground modification alternatives such as deep dynamic compaction, vibratory compaction, and pre-consolidation were determined to be economically unfeasible. Recommendations were made to replace the conventional thickener with a high capacity, cone thickener. (Hydro-Triad, Ltd., 1998)
