About

reOsiris Inc. is a mining waste recovery and environmental restoration company established in 2017 and headquartered in Toronto, Ontario. The company’s mission is to restore land, lakes, and rivers impacted by historic mining activities back to their natural conditions. reOsiris specializes in tailings remediation processing plant design, traditional mineral processing, complex metal phases, sampling programs, engineering, equipment design, fabrication, construction, commissioning, and operations, with a focus on developing innovative and sustainable solutions for the mining sector.

Project

Through support from OCI’s Critical Industrial Technologies (CIT) Development and Commercialization Program, and in collaboration with Cambrian College Centre for Smart Mining, reOsiris is developing and demonstrating a mobile tailings reprocessing facility capable of extracting valuable metals from mine waste at a rate of one metric tonne per hour. The system integrates artificial intelligence (AI) and robotic automation to enhance resource recovery while reducing environmental impact. Designed to be modular and mobile, the facility can be deployed to mine sites to efficiently process ultra-fine tailings that are typically uneconomic to recover. By combining advanced process design, automation, and AI-driven optimization, the project enables more sustainable management of historic and active mining waste streams.

Impact

This project advances reOsiris’s AI-driven resource recovery technology toward commercialization by delivering a validated, mobile solution for tailings reprocessing. The outcomes support improved recovery of critical minerals, reduced environmental liabilities, and more sustainable mining operations. By enabling the reprocessing of mine waste and supporting circular economy practices, the project aligns with Ontario’s critical minerals strategy, creates new opportunities for the mining sector, and positions reOsiris as a leader in advanced AI-driven resource recovery.
