First gold project in China by a western entity

This project is Sino Gold’s flagship project and is considered to be the largest known Carlin-type deposit in China. Jinfeng is the second largest gold mine in China with production of 180,000 ounces per annum.

Ausenco was involved in the design and construction of the 1.2 Mt/y gold treatment facility including comminution, flotation, BIOX® leaching, CIL, mercury scrubbing, neutralisation, cyanide detoxification and waste disposal.

Ausenco’s scope included responsibility for the management of the engineering for the process plant and infrastructure, global procurement and logistics, construction management and commissioning for the facility.

The plant is the first western executed gold project in China. As such, it has involved extensive collaboration with Chinese authorities and local engineering organisations.
