We would like to thank all those who participated and followed the Rio Tinto Ore Upgrading Challenge. We are particularly grateful to the winners of Stage 1 (Concepts), the HavenSter Team (Hendrik Havenga, Simon Streicher and Danie Murrey) and Eric Agorhom's Team (Eric Agorhom, Clement Owusu, and Jim Pae Lem), who tried hard to meet the Challenge objectives.
Unfortunately, in Stage 2 (Feasibility), neither of the winners of Stage 1 was able to produce an ore concentrate of the quality desired by Rio Tinto. Therefore, there is no Stage 2 winner.
Exploiting Earth’s resources in an efficient and responsible way is increasingly difficult. For this reason, Rio Tinto remains committed to Open Innovation. Another Rio Tinto challenge remains open to ideas, and more may appear in the near future.
