The Lihir gold mine is located on Niolam Island, Papua New Guinea (PNG), approximately 900km north-east of Port Moresby. The gold mine was managed by a subsidiary of Rio Tinto until late 2005, and the operatorship was then handed over to Lihir Gold. Australian miner Newcrest Mining acquired Lihir Gold in a $9bn deal in 2010.
The Boddington gold mine (BGM) is an operating open-pit mine located 130km from Perth, Western Australia (WA). It is one of the largest gold-producing mines in the country. The $2.4bn project was initially a three-way joint venture between Newmont Mining (Newmont), AngloGold Ashanti (AngloGold), and Newcrest Mining.
The process of smelting now involves removing impurities from the gold using a combination of pressure, heat, and several chemicals. It entails ore processing and the removal of impurities. Four steps are used, including gold processing, pre-smelting chemical removal, impurity removal, and melting.
