Evaluation of grinding circuits for iron ore - SciELO One circuit had two mills installed in series with the first mill operating in an open than the series circuit with an additional 4.3% throughput in the flotation feed. Each line has an independent grinding circuit with two ball mills and three
ASARCO Milling SAG mills use larger pieces of ore to break up the smaller pieces first flotation cell goes on to two more flotation cells to recover as much copper as possible.

Model Predictive Control of SAG Mills and Flotation Circuits Precise control of SAG mill loading and flotation cell level is critical to maximize production and with the balls and from autogenous rock on rock grinding. Typically a number of cells are arranged is series so that as the pulp flows through
