Apr 15, 2020· The Macraes Process Plant recovers gold by concentrating the metal into a relatively small fraction of flotation concentrate, oxidising the reground concentrate in a pressure oxidation autoclave, washing the oxidised residue and then utilising a carbon-in-leach process to recover gold from the residue. In detail the plant comprises:
Macraes Mine in East Otago is New Zealand's largest gold mine, and consists of a large scale opencast mine opened in 1990, and a newer underground mine, opened in 2008. It is situated close to the settlement of Macraes Flat and is owned by OceanaGold Corporation.. Gold production averaged 193,000 Troy ounces/year for 2008 through 2010.

The Macraes Mine is New Zealand’s largest gold mine, and is owned and operated by Oceana Gold (New Zealand) Ltd (OceanaGold). The mine consists of a large scale open cast mine, underground mine (Frasers Underground), waste rock and tailings disposal areas and supporting mine infrastructure.
As such, closure and rehabilitation are integral aspects of the mine design process at the Macraes Operation. By including aspects for closure and rehabilitation early in the mine design process, significant environmental impacts can be avoided such as backfilling of mined open pits instead of creating new waste rock stacks and thereby limiting the environmental footprint of the mine.

Although there is a strong benefit in establishing N-fixing plants on mine substrates the unique characteristics of the fresh tailings at the Macraes mine site does seem to support their early establishment. There are a number of factors that may be responsible: legumes rank amongst the most sensitive plants to arsenic toxicity.

The Macraes POX plant is still in operation as of 2015. It has not been expanded but now treats sulfide concentrates from the Macraes Mine (approximately 24 t/h at 8.5% S) and the Reefton Mine (approximately 12.5 t/h at 24% S). Complete oxidation of sulfides is targeted in order to convert iron to the ferric state for arsenic stabilization.
