The Ecohydrology Research Group at the University of Waterloo and Knight Piésold Ltd. will join forces in order to build a new research collaboration to characterise samples of the blended residue streams from the lithium mining and assess this material as a by-product for use in land reclamation applications. The proposed Engage project targets the development and validation of a simple, rapid and cost-effective method to assess the re-processing potential of blended residue sample under variable amendment additions for reclamation uses. The results will be instrumental in providing guidance to characterize the blended residue sample from lithium concentrate processing and assessment for use of this by-product in future land reclamation purposes. The outcomes of this project will also generate significant interest in the fields of land reclamation and site rehabilitation. They will be instrumental in providing guidance to the implementation of mining residue material strategies in support of mining industry's environmental footprint efforts. This Engage project will lay the foundation for subsequent joint projects that will yield the scientific knowledge needed to enable the implementation of in situ re-processing of lithium mining residues as an effective, reliable and cost-saving technology. ****
