The Boddington gold mine (BGM) is an operating openpit mine located 130km from Perth, Western Australia (WA). It is one of the largest goldproducing mines in the country. The project was initially a threeway joint venture between Newmont Mining (Newmont), AngloGold Ashanti (AngloGold), and Newcrest Mining.
Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit).
