During the second half of the 1990's, large diameter SAG mills, for example 36' in diameter and greater, began to proliferate the industry, amply demonstrated by the commissioning of the KCGM, St Ives, Alumbrera, Ernest Henry and Batu Hijau SAG mills. The first of the 38' mills entered service at the Antamina operation in the late 1990s ...
7. Conclusions Batu Hijau is a world-class porphyry Cu deposit in an island arc setting; it is typical of this deposit type in most features, including igneous association, morphology, and styles of alteration and mineralisation. The Batu Hijau discovery resulted from systematic and comprehensive stream sediment and creek float sampling surveys.
This has been the case at PT Amman Mineral's Batu Hijau SAG mills, where frequent variations were observed due to size segregation in feed. Furthermore, SAG mill behaviour and the relationship ...
