The Lihir Island Open Pit Gold Mine, a unique site situated 900 km from Port Moresby, Papua New Guinea, rests on an extinct volcanic crater that is still geothermally active. This intriguing location is where most of the refractory ore is produced and treated using pressure oxidation, followed by a conventional leach process to recover the gold.

Gold must be leached from refractory ore by subjecting it to high temperature, high pressure, and/or oxygen. Newmont treats refractory ore using an autoclave or a roaster.

The Challenge

One of the methods used by Newmont is the autoclave. This process begins with the heating and feeding the slurry into the autoclave. A chemical reaction is initiated by applying high-pressure steam, water, and oxygen, which oxidises the sulphide material. The slurry is then cooled and reintroduced into the process for leaching.

Regularly, the autoclaves are partially shut down to conduct routine maintenance or repairs, and it is crucial to seal off the Autoclave to ensure a safe environment for technicians to work.

Inflatable insulated isolation barriers

The shutdown specialists at the Lihir Island Mine contacted Giant Inflatables to design two sets of isolation barriers. One set was standard, while the second set was insulated using an aluminised mylar fibreglass hybrid cloth to reflect the heat and protect the inflatable isolation barrier and, more importantly, the workers inside.
