Learning Outcomes

Designed specifically for people with a basic understanding of comminution concepts and Moly-Cop Tools.  This 2-day short course includes a detailed overview of the various theoretical and practical aspects related to the design and optimization of industrial grinding circuits.  Starting from the classical comminution theories as proposed by Von Rittinger to the more general theories of Kick and Bond.

The course also focuses on detailed population balance grinding models.  Further, some empirical hydroclassification models are reviewed and included in a wide variety of closed-circuit grinding simulators, ranging from the traditional conventional single stage to the more complex, multistage semiautogenous circuits.  Each session of the short course contains several practical exercises (laboratories) so as to provide participants direct, hands-on experience the Moly-Cop Tools 3.0 software.


Moly-Cop Tools Course held in Belo Horizonte, Brazil
