Benefits of Dynamic Process Simulation for Mineral Industry

In a typical application of steady-state modeling, numerous configurations of the grinding circuit may be produced and analyzed in order to select the best equipment configuration. When the final configuration is selected, the steady-state model may be run for different cases involving different ore types, mineral contents or production rates.

Zalta™ Grinding Aids

Zalta grinding aids lead to gains in grinding productivity by reducing cohesion and adhesion in the ore slurry. This decreases the viscosity and/or yield stress as the slurry moves through the ball mill, improving grindability by both cascading motion and freefall ball-striking motion. Key benefits include:
