Sun Metals Zinc Refinery – Townsville, North QLD
Located 15 km south of the city of Townsville in North Queensland sits one of Australia largest Zinc refineries, owned and operated by the Korea Zinc Company the Sun Metals Corporation in Australia has an annual production of approx. 225,000 tonnes of special high grade zinc metal.
In December 2018, the Sunmetals Zinc Corporation with the support of the Queensland government announced a $300 million expansion to their refinery with the outcome of the investment expected to increase the refinery’s zinc production 17% from 225,000 tonnes per year to 270,000 tonnes.
The $300M investment represents a significant opportunity for both the Sunmetals Corporation and Queensland economy with 350 jobs created during the construction phase and an additional 100 permanent operational positions created once the project is completed by mid-2021.
KEY FEATURES OF THE PROJECT
The expansion project aims to deliver new facilities at the existing Sun Metals Corporation zinc refinery, including:
- A new electrolysis building, ferric oxide facilities, and leaching and purification areas.
- The electrolysis and ferric oxide facilities are being constructed to support and replace the existing structures, while the leaching and purification works will assist in accommodating more volume through the plant.
- These works underpin the work required to increase production overall by 17% at the plant.

The synergies created following the acquisition of the Uni-span business in November 2019, from both an equipment and engineering perspective, positioned the Acrow Group of Companies to the centre of negotiation with the major sub-contractor on site – Western Downs Contracting. Through innovative engineering and design utilising both the Acrow Supercuplok and the Uni-span MK system in parallel, we were able to present and demonstrate to the customer a formwork solution that not only fulfilled the needs from a cost perspective, but also a practicality sense in relation to the application. This was most evidently demonstrated by the use of the MK System for the trusses in relation to the travelling gantry which were built and assembled on site and then craned into position. Adopting this methodology enabled the structure to be built minimising obstructions at ground level and allowing the lower level works to continue simultaneously.
