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, is continuously looking for new deposits of mineral sands to mine, which contain valuable heavy minerals such as ilmenite, zircon and rutile. These deposits can be high in grade but small in size, or of considerable size but low in grade and located in difficult to mine areas, creating social and environmental concerns.

Traditional sand mining methods include significant infrastructure and disruption to the area in order to perform initial mineral concentration on-site, using wet separation methods. In this challenge, we seek your ideas for conceptual solutions related to new mining approaches whereby mineral sands are mined and processed using unconventional means that minimize or eliminate the need for water, infrastructure or other disruptions to the area.

The Guidelines and Technical Description sections of this challenge further outline the key process steps we are exploring, including excavation, initial separation/concentration, and backfill of materials. We are looking for conceptual solutions and novel ideas for addressing these process steps, including potential combination approaches. Your ideas can address one part of the process or all of the elements that are defined to be within scope. 

This is an Ideation Challenge, where a guaranteed $25K award pool will be shared among winning solutions selected by Rio Tinto. Winners (and all Challenge participants) will retain ownership of their ideas, but provide Rio Tinto with a royalty-free, non-exclusive right to your awarded idea. There is also a high likelihood that Rio Tinto will launch a follow-on, larger-scale challenge during 2020, with up to $500k in awards for more complete and validated solutions. The later challenge would be open to participants in this first challenge, as well as any other innovators who are interested in participating.
