The NVRO Process™

Turning Mine Tailings into Critical Metals Supply

Why the Industry Needs New Processing Solutions

Governments and industries worldwide have increased efforts to secure sustainable supplies of critical and strategic metals. Many of these metals already exist above ground in current and historical mine tailings, readily accessible and able to be processed. 

Using our propriatory NVRO Process™, we recover critical and strategic metals from mine tailings, transforming mine waste into new sources of critical metals supply while at the same time reducing environmental risk and liability.

How the NVRO Process™ Works

NVRO Process

Step 1

Feed Material

Mine waste, tailings and selected sulphidic materials.

Step 2

Metal Recovery

The NVRO Process™ concentrates and recovers valuable metals through a low-temperature hydrometallurgical process.

Step 3

Valuable Products

Production of metal-rich concentrates and recoverable products.

Step 4

Environmental Outcomes

Reduced sulphide content and stabilization of environmental liabilities. >95% AMD (Acid Mine Drainage)
