CASE STUDY: 29Metals

GOLDEN GROVE MINE

Golden Grove Mine owned by 29Metals is situated in the mid-west region of Western Australia, 450km northeast of Perth. This high-grade copper, gold, zinc, lead and silver mine is a long-life producing asset with a current mine life of 10 years. The original deposit was discovered in 1971 with mining operations beginning in 1989. Golden Grove, formally known as Goassan hill consists of both open pit and underground mines.

29Metals reached out to Minetek for a solution to achieve their short-term ventilation needs whilst also implementing a system that would be capable of achieving their long-term goals. With strict project limitations around infrastructure and power constraints, Minetek needed to achieve specific targets whilst also offering a solution that could provide operational savings for their business.

Minetek has been able to support Golden Grove Mine by providing a ventilation solution around their tight infrastructure while still delivering an airflow that would meet and exceed their needs for the foreseeable future. This allowed Golden Grove operations to meet and exceed development targets, minimise shutdowns and reduce operational and energy costs.

Minetek solution for Golden Grove Mine

The site needed the solution engineered to meet both their short and long-term ventilation requirements and life-of-mine targets. Minetek worked closely with 29Metals & Golden Grove Engineers, to provide a turnkey ventilation solution within their electrical capacity to meet all future requirements.

Minetek supplied 2 x 1770mm large Primary Booster Fans with a supporting electrical substation and soft starters. Both the motor and soft starter on the Primary Booster Fans have an output rating of 560kW and work within the electrical supply capacity limitations. Our Anti-Stall Chamber prevents the aerodynamic phenomenon of a stall, which occurs when a fan operates beyond its performance limits and flow separation occurs around the blade (air bubble is formed). The Minetek Anti-Stall Chamber does not allow the stall bubble to form by constantly peeling air through the impellor.

Minetek’s Primary Booster Fans are fitted with our patented POD technology. This technology regulates airflow regulation without the need for VSD infrastructure and allows gradual ramp-up to meet ventilation requirements over the life of mine, optimising performance and efficiencies. Our POD system (power, performance & pressure on demand) ensures that these fans are always running at peak efficiency, no matter what conditions they’re facing. Our engineering capabilities ensured end-to-end support including commissioning, supply, installation and ongoing support.

We are always looking at new innovations and technologies that will benefit both us and our clients. Minetek has been able to display that with the use of their modern ventilation technology, where we can look to see production increases through faster re-entry times and reduced capital costs in the total life of the development, delivering value to both us and Mincor.

I have used these evaporators very successfully at mine sites where I have worked in the past. They are an extremely reliable unit and worked above expectations in the environment where we had them set up. As for spray drift/mist this can be controlled by the weather monitoring systems that are available with the units. Additionally, how you set them up and the amount of fall you can achieve allows for more moisture to be stripped from the droplets]will greatly benefit your overall evaporation rates.

I can honestly say I have found MINTEK WATER a very professional organisation in all the dealings that I have had with them. They have always been proactive and looked for and suggested alternatives to assist me in the delivery of my projects whilst still working on the original concept.
