Recovering high-value metals from mining waste

We’re turning a liability into an asset with an efficient, flexible technology that uses electricity to reclaim valuable metals from waste produced during the mining process.

Molten Oxide Electrolysis (MOE) for High-Value Metals Production

The world’s large-scale mining operations produce over 100 billion tons of solid waste per year, and the current waste storage and treatment facilities are unprofitable. However, this mining waste, known as slag, often contains useful and precious resources. The challenge is reclaiming them.

We are empowering mining companies to recover value from a liability while advancing a circular economy for the metals industry. MOE uses electricity to selectively extract valuable metals from complex, low-concentration materials that are currently considered waste. Through leveraging a natural by-product of metal production, mining companies can create new revenue streams while reducing the financial liabilities of slag. With MOE, the metals industry has a scalable, cost-competitive and sustainable solution to produce a variety of metals and alloys from a wide range of feedstocks.

Key Benefits

Profit from Waste

The cost of slag storage and treatment facilities is a drain on the bottom-lines of mining companies. Our high-value metals solution will instead turn mining waste into an asset because MOE can selectively extract precious resources.

Efficient Solution

Using MOE cells to recover high-value metals from mining waste is substantially more efficient and cost-effective than the incumbent methods of producing ferroalloys such as ferroniobium and ferrotantalum.

Flexible Technology

MOE is modular, scalable and can be tailored for use with multiple target metals. Our MOE cells can be scaled by adding new cells. This allows for a uniquely customizable and tailormade solution for high-value metals production.
