Production from the Near Surface deposits commenced in the second quarter of 2023, with processing of the ore at the Macassa mill. The AK deposit has been added to the mining profile starting 2024 with ore forecast to be trucked and processed at the LZ5 mill circuit at the LaRonde complex starting in the second half of 2024.

The model then yields - the operating parameters (e.g. capacity and energy consumption of the mill, torque of the rolls, bulk density of the flake), which will result from the operation of the mill.
Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N. N is related to mill diameter which decreases with larger diameters k a constant equal to π /4. A chart showing rod mill capacity vs. mill diameter [image: (135-8-5)] A chart showing rod mill capacity vs. mill length
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...

Analysis of ball and pulp flow in ball mills indicates that three factors may become critical with increasing mill diameters: ball size, fraction critical speed, and average pulp flow velocities. Ball diameters may need to be decreased and fraction critical speeds increased with ores which show decreased breakage rate coefficients above 1.2 mm (14 mesh). …
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
Decreasing the inclination slows the movement across the table thereby decreasing capacity but improving efficiency. Above 12 mm, dry screening is preferred. ... The material density is 150 lb/ft 3 and the …
