We have been accepted into BHP's Comminution Open Call Challenge as a finalist. This challenge seeks innovators with ideas to enhance mineral extraction processes by reducing energy consumption or increasing throughput in rock comminution. We will collaborate with BHP to explore the potential of High-Pressure Slurry Ablation (HPSA) as a comminution technology. The study will not only assess the applicability of HPSA at BHP assets but will also explore other niche applications across the value chain to maximize value addition. This is an exciting opportunity for Disa to work on a project that has the potential to make a significant impact in the industry. #Comminution #BHP #Mining #Innovation
Congratulations Comminution Open Call Finalists! We went out into the world to find innovators with ideas to help us reduce energy consumption or increase throughput by changing the way we crush, pulverise and grind rocks for mineral extraction. Finalists will work together with us to understand the opportunities of their comminution technologies. Think & Act Differently (TAD) are partnering with Sedgman Pty Limited to help us complete a study to compare twelve technologies. The study will understand their potential for materially improving overall comminution system capital and operating costs at scale. We will not only focus on comminution applicability at BHP assets, but also consider other niche applications across the value chain to add additional value. Think & Act Differently work together with innovators in different ways to accelerate technologies that could help us deliver resources more efficiently.
