Epiroc faces a challenge shared across the mining industry: how to efficiently separate hard metal components – mainly tungsten carbide and cobalt – from the steel bodies of used drill tools.
These tools are built for maximum durability. Hard metal buttons are deeply bonded into steel to perform in the toughest environments. But what makes them strong also makes them difficult to recycle. Current methods, such as mechanical techniques and induction heating, are energy-intensive and not optimized for large-scale or complex tools.
Epiroc now seeks innovative, scalable, and sustainable methods to separate hard metal from steel – ideally deployable at existing operational nodes, such as service centers or grinding shops.
Solutions can be decentralized and low-cost for remote sites, or centralized and high-capacity for mining hubs. The goal is clear: enable efficient recycling, reduce waste, and secure a sustainable supply of critical materials like tungsten, cobalt, and nickel.
Do you have an idea that could unlock the next generation of hard metal recycling?
