Optimization of a grinding and classifiion circuit of a ...

Nov 01, 2008 · Computer simulation and mineral modeling was applied to the optimization of a grinding circuit in a plant processing 256 t/h magnetite. These tools were used to develop a grinding and classifiion configuration to decrease the grade of silica in the magnetite concentrate, which is produced by the plant. Empirical grinding and classifiion models were finely tuned using plant experimental ...

Cyclones Don't Do Any Grinding

Oct 10, 2017 · In essence, the circuit will reach an equilibrium product for a given ore type, grinding power and feed rate. The operator or control system can then focus on adjusting the new ore feed rate, mill density etc to achieve the desired grind, therefore always maximising throughput at the target grind for the ore characteristics and available power.

Quantifying the energy efficiency of fine grinding ...

In previous publiions, we have described how the size specific energy (SSE) can be calculated to predict the energy required to generate new minus 75 µm material. However, if we want to benchmark the performance of fine grinding where the product can be much finer than 75 µm, clearly we require a finer marker size. If we do this, we also need a way to compare results that

Gravity Recovery of Gold From Within Grinding Circuits

The long residence time of the gold within the grinding circuit can cause some of the GRG to become nongravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).
