A 135 m diameter tailings thickener for expansion of a copper concentrator was designed and built in the
Chilean Andes. Design challenges included high seismicity, the presence of an existing fill layer containing
large particles placed in thick lifts over a sloping ground surface with limited compaction control about
10 years prior to construction of the tailings thickener, and a previous history of settlement problems of two
neighbouring thickeners. Solutions adopted for the new thickener included the use of piles to support the
concrete central core of the new tailings thickener, transition concrete slabs to support the geomembrane
lining system where it was connected to the concrete central core to prevent rupture of the liner in the event
of seismic settlements, and continuous reinforced concrete elements for the perimeter concrete water
collection system. The thickener has been built and successfully hydrotested.
