The Cosmo Howley gold mine in the Australian desert required a supply of 8 bar oxygen to help leach gold from crushed soil. The solution was to provide a 5 TPD mobile oxygen plant, adapted to local operations. I designed the plant, sourced its key elements from Atlas Copco, AirSep, Haug AG, and assembled them onto a road trailer. The remote oxygen plant was tested, and then commissioned on-site in difficult operating conditions with success.
