Rio Tinto Ore Upgrading Challenge

Rio Tinto seeks economically-viable new technologies to increase titanium dioxide content in ilmenite ore from 32% to 50% or better.
Stage 2 Launch

Challenge Overview

Rio Tinto supplies the metals and minerals that help the world to grow. Rio Tinto Iron and Titanium (RTIT), the group originating this challenge, provides ilmenite ore containing titanium dioxide as a raw material to pigment producers. Titanium dioxide (TiO2) is non-toxic, biologically inert and used by downstream pigment producers as a coloring or opacity agent in paints, plastics, paper, and other materials. 

In this challenge we seek your ideas for how to cost-effectively improve TiO2 content in our ilmenite ore (from 32% TiO2 content to 50% or better) by isolating and separating out lower-quality hematite inclusions (lamellae) from the ore matrix and liberated gangue (non-valued) material. Given the scope and scale of our operations, the business opportunity for successfully solving this problem is very large.

This two-stage challenge will provide innovators with the most compelling ideas funding to demonstrate feasibility and may ultimately result in commercialization. In our Stage 1 Challenge, participants will provide a non-confidential submission that describes the proposed approach to increasing TiO2 content in ilmenite ore. Up to three (3) of the most compelling concepts will be selected to advance to Stage 2, which will be conducted under mutual non-disclosure agreements. Each accepted Stage 1 winner will receive $50,000 USD to support their work in Stage 2, which is focused on demonstrating initial feasibility for the proposed approach via both written descriptions and results of testing using Rio Tinto ore samples. At the end of Stage 2, Rio Tinto will select the challenge winner and award one winner up to $200,000 to support additional development under a negotiated co-development agreement. Rio Tinto will also provide the winner with technical support and the opportunity to collaborate with Rio Tinto R&D scientists and engineers. Should this solution prove technically and commercially feasible, Rio Tinto may propose a follow-on agreement with the winner for commercialization and scale-up. 

Solving this problem represents a significant opportunity for both Rio Tinto and the challenge winner. We look forward to your engagement and ideas!
