Power-based modelling of single-stage AG and SAG mill

Operating data from the single stage SAG mill at Anglo American’s El Soldado mine in Chile was evaluated and compared to four published power-based comminution models. Case studies from literature for other single stage SAG or AG mills were then evaluated in the same four models.

GRINDING: Outotec builds world's largest SAG mill

The mill will be operated as a single stage SAG mill (primary and secondary duty combined) with very high throughput made possible by the use of Outotec’s patented Turbo Pulp Lifter (TPL™) technology. The grinding mill will be installed during 2014 at First Quantum’s Kansanshi copper mine in Zambia.

Kansanshi copper-gold mine, Solwezi, Zambia, East

Outotec delivered a SAG mill, which was considered to be the world’s biggest SAG mill, for the mine under a contract awarded in 2012. Integrating Outotec’s patented Turbo Pulp Lifter (TPL™) technology, it can be operated as a single-stage SAG mill performing both primary and secondary grinding functions.
