At grinding time less than 4 min, 3.00 and 4.00 cm ball sizes produce a limited size range with the feature that as ball size increases, the larger fragments do not break, resulting in larger values of k and λ, and indicating an inefficient ballparticle interaction. this situation could indicate that when using 3.00 and 4.00 cm grinding media.
The runofmine extracted from the ground requires further processing in order to make a marketable product. this preparation is called mineral processing. thus, ores must go through a number of different operations to obtain the final products: comminution or size reduction, size separation, concentration or beneficiation, and dewatering.
