The US$2.6 billion project, a joint venture between Fortescue Metals Group subsidiary FMG Magnetite and Formosa Steel, was green-lit earlier this year.

With premium magnetite iron ore reserves, once fully operational, the mine is expected to produce 22 million wet metric tonnes per year. Delivery of the first ore is expected in 2022. 

The equipment order includes Weir's Enduron high-pressure grinding rolls (HPGRs) and GEHO pumps. These could help reduce energy consumption and wet tailings waste by more than 30% compared to traditional mining technologies, Weir claimed.

Weir Group CEO Jon Stanton said this was the company's "largest-ever individual mining order".

"Fortescue challenged us to help create one of the most energy- and cost-efficient magnetite ore processing facilities in the world. Our engineers have worked relentlessly to design a solution that is truly innovative - delivering significant energy, water and cost savings," he added.

The Weir Enduron technology, designed and manufactured at the company's facilities in the Netherlands, offers an alternative to conventional mills in comminution circuits.

According to Weir, the HPGRs require around 40% less energy, their wearable components last longer and the maintenance time required to replace worn out parts is lower than with traditional solutions.
