Andy Well Gold Project

Scope of Work

GR Engineering was appointed by Doray to undertake the engineering, design, procurement, construction and commissioning of its new process plant facilities for the Andy Well Gold Project. The project required the development of a process plant capable of treating 165,000 tpa of underground ore.

The Andy Well process plant is designed for a nominal 20 tph milling rate. Run of mine material is fed to the crushing plant at a design rate of 60 tph with crushed ore storage capacity installed to provide a physical break between crushing and milling operations.

Ore is passed through a two stage crushing circuit. Crushed ore is stored in a fine ore bin with a live capacity of 360 tonnes. The grinding circuit consists of a single stage 500 kW ball mill. Gold recovery consists of both a gravity circuit containing gravity concentrators and intensive cyanidation unit and a conventional carbon in leach (CIL) arrangement consisting of seven CIL tanks. Loaded carbon is stripped of gold using a Split Anglo type elution circuit and gold will be subsequently recovered from the cathodes of the gravity and elution electrowinning cells.

GR Engineering commenced the EPC design and construction of the gold treatment plant in September 2012 and commissioned the project in July 2013, on budget and ahead of schedule.
