"Osmoflo has delivered an important piece of infrastructure that will support the ongoing sustainability of our mining operation. Roy Hill has also engaged Osmoflo to maintain and operate the plant which demonstrates Osmoflo’s end to end capability." said Roy Hill Project Director Paul Laybourne.

Challenge With its integrated Mine, Rail and Port facilities, Roy Hill has the capacity to deliver 55Mt of iron ore per annum.  This must meet stringent quality standards and in particular the ore must be washed to remove chloride based salts before shipment. The water available to the project is suitable only for the first 4 years of mine life and is predicted to deteriorate over time with increasing chloride based salt levels.  Because of this., Roy Hill require a water treatment solution to remove some of the chloride from the water coming from the aquifer to enable final ore washing.

Solution  The EPC contract involved the delivery of a desalination and blended water treatment plant at the Roy Hill mine site with capacity up to 20 MLD. The plant treats bore water to produce treated water that is suitable for use by Roy Hill's processing plant. The project also includes the installation of a 4.3km pipeline that will be used to pump the brine from the plant to a managed aquifer recharge system. 

Following the completion of the plants construction, Osmoflo will provide the subsequent operational, maintenance and whole-of-life asset management of the plantfor the life of the mine.

Result  Fabrication of the 20 MLD brackish water reverse osmosis plant and associated equipment for Roy Hill took place at Osmoflo’s manufacturing facility in South Australia. The plant was then be transported over 3,400km to the Roy Hill site with the project completion in early June 2019.

"Given the remote location and logistical challenges faced on this project, we are pleased to have successfully delivered this project to a high standard and are now fully committed to operate the plant and provide quality process water to the Roy Hill mine." said Chris Reynolds, General Manager of Projects."With the invaluable experience gained through the construction phase, Osmoflo is well placed to manage similar challenging opportunities in Australia, and around the globe."

Carmine Ciccocioppo, Chief Operating Officer, at Osmoflo, said that the company is delighted to have achieved this significant milestone for the Roy Hill mine site, and is looking forward to continuing to build on the strong working relationship with Roy Hill by providing consistent and reliable operations and maintenance services for the next 20 years and beyond.
