Roy Hill was recognised at the Australian Mining Prospect Awards this evening in Perth.
Roy won the Mine Project Success of the Year Award for the WHIMS Expansion Project (WHIMS 1.5). The pioneering of the Wet High Intensity Magnetic Separator (WHIMS) plant in December 2019 allowed capture of high-grade ultrafine iron ore units which would otherwise have ended up as waste.
When the original WHIMS first processed ore in December 2019, Roy Hill was the first Australian iron ore company to use magnetic separation in a hematite mine at that size and scale, reducing waste and increasing production by approximately 4mtpa.
Roy Hill has since expanded the plant to include two-stage treatment via magnetic separation and a spiral building to recover misplaced fines and high-grade ultrafines from the +125um size fraction via gravity separation.
WHIMS Expansion plant (WHIMS 1.5) opened in April 2022, is painted pink in support of breast cancer research, and was officially named the Watroba WHIMS Plant in honour of Board Member Tad Watroba.
