The aftermarket contract follows Weir's success in winning a record £100 million order for original equipment for the Iron Bridge project in 2019, including its innovative Enduron high-pressure grinding rolls (HPGRs) that enable dry processing of ore and use at least 30% less energy than traditional alternatives.
Both the aftermarket order and revenues will be recognised over the seven year period of the agreement which starts in 2022, in line with the project's initial production.
Weir Minerals president Ricardo Garib described the contract as another landmark order for Weir.
"Having helped design an energy and water efficient magnetite processing plant, we are delighted to provide operational support for Iron Bridge from 2022," he said.
"It is an excellent example of the value that Weir's innovative engineering and close customer support can create for all our stakeholders and reflects the key role we have to play in making mining operations more sustainable and efficient."
Weir's Enduron HPGRs are increasingly replacing conventional mills in comminution circuits.
In addition to their energy and water savings they also reduce grinding media consumption, while their wearable components last longer, reducing maintenance costs. Additionally, HPGRs contribute significantly to carbon dioxide emission savings.
"We know comminution is one of the most energy intensive parts of the mineral process and with our Enduron HPGRs we have a unique ability to offer significant cost, energy and water savings to customers around the world," Weir Minerals Netherlands Stuart Hayton said.
"As the mining industry evolves we are committed to continuing to innovate, reducing miners' costs and environmental impact."
Weir now has more than £200 million of orders from the Iron Bridge project, including its Enduron HPGRs, GEHO and Warman pumps, Cavex Hydrcyclones and Isogate valves.
To support the project and future growth, Weir will build a new service centre in Port Hedland, which will provide employment and training opportunities in the area, with a particular emphasis on supporting greater Aboriginal representation in the broader mining workforce.
Shares in Weir rose 2% to 1709.5p in London overnight, valuing the company at £4.4 billion.
