Ore Processing Challenges in Gold Operation Grinding Circuits. By Scott Ferguson 06.16.2020. Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput.

Abstract It is difficult in run-of-mine (ROM) milling circuits to control the particle size of the product and other important variables because the ore fed to the mill also acts as the main grinding medium. This results in significant uncontrolled disturbances and uncertainties. Before the μ-controller synthesis and analysis methodology can be applied to this multivariable …
