Rio Tinto: Sustainable Mine Water Remediation

Deadline: Thursday 28th April 2022

Rio Tinto is looking to partner with experts to find solutions that can selectively target and efficiently remove selected constituents from mining influenced water.

 The use of selective technologies will enhance water recovery, reduce residual waste and drive the recovery of valuable resources from the water. This will deliver improved environmental outcomes, generate new revenue streams and offset closure costs.

 The goal of this campaign is to identify, support, validate and eventually implement treatment solutions that achieve:

•  Specific removal of contaminants known to adversely affect downstream treatment processes and which limit or impede end uses and recovery processes
•  Selective separation of high value constituents (e.g. Cu, Ni, Co, Li, Zn, Mn and rare earth elements) from water and wastes in a high-quality form that can be readily commercialised
•  Develop new revenue opportunities from the development of local opportunities such as the production of a fit-for-purpose water supply for communities, industries, and agriculture

 We want to partner with solution providers to develop projects that can overcome current challenges at a number of our closed assets and emerging challenges at some of our currently operating assets that are transitioning to closure. These projects will play an integral part in the R&D pipeline of opportunities for the next three years and beyond.

Rio Tinto is willing to fund and/or cost share individual projects from US$50,000 up to US$2 million. Funding may be made available as a mix of cash and in-kind (e.g. site access for prototyping or testing, subject matter expertise, wastewater samples).
