Angas Zinc Mine Water Treatment, SA
The Client
Terramin
Terramin has been focused on zinc for more than 10 years.
For its acquisitions, Terramin follows strict criteria designed to minimise capital costs and start up time. The criteria include deposits of high grade core, proximity to infrastructure such as ports, roads, water and power, and potential for expansion.
The Angas Zinc mine is located 2km outside the rural town of Strathalbyn, 60km south-east of Adelaide.
The Client's Needs
The 400,000 tonnes per annum Angas Zinc project, about 45 minutes from the city of Adelaide in South Australia was commissioned successfully in July 2008.
Annual ore throughput at the AngasZinc mine has reached target throughput during late 2009: 50,000 tonnes of zinc and 20,000 tonnes of lead concentrate annually.
As part of mine plan compliance (MARP), Terramin reduced its environmental impact by restricting offsite disposal of suitable quality water and recycling water used in processing operations. Groundwater quality and levels are also monitored to remain unaffected.
Veolia's Solutions
Veolia Water Technologies were awarded the contract for the design, build, and commissioning of a fully containerised reverse osmosis plant including pre-treatment as well as spare parts.
The Reverse Osmosis plant was commissioned to produce 240 KL/day of treated water for use within the Angas Zinc mine located in Strathalbyn, South Australia.
The feedwater, from mine water disposal, is high salinity brackish water, and has high raw water turbidity and iron levels. The site also have remote monitoring and local service support.
