Comminution Circuits for Gold Ore Processing

2016-1-1  Such a circuit can counteract the effects of harder ore, coarser ore, decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the

Ore Processing Challenges in Gold Operation

In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput. This is essential for driving the overall efficiency of the operation because the process of grinding and crushing ore — known as comminution — is on average the highest energy step in mining.
