Thickener – Montepuez Ruby Mine

Site: Brownfields


Unit Process


ADP was commissioned by MRM to procure and install a 30m high-rate thickener along with it’s flocculant plant.

The thickener had to interface with the clients existing degrit modules and existing 18m thickener which was made redundant and used as a process water tank.

The original project schedule was 43-weeks however, the client’s early Geotech work had failed to detect an old slimes settling pond, from the clients original prospection plant in the area, which had been buried. Hence additional time was taken to fully excavate the unstable area and back fill with rock to obtain the levels of compaction required for the thickener civils.

The plant was successfully commissioned in December 2019.
