Measuring and modelling the impact of primary crusher …
Comminution circuits generally have a coarse ore stockpile after the primary crusher to decouple the relatively uneven mined ore supply from the downstream comminution and concentrator circuits which require a stable feed. Whilst this assists with evening-out throughput disturbances, it can influence the size distribution presented to the ...

The coarse ore stockpile assists with evening-out throughput disturbances; however, it can influence the size distribution presented to the downstream comminution circuits through size-segregation effects. In the case of Autogenous (AG) and Semi-autogenous (SAG) circuits this is particularly important (Morrell and Valery, 2001). However, what ...

A 3D cellular automata ore stockpile model
The segregation function is a simple relationship that splits an ore into a coarse fraction and a fine fraction of equal volume. The characteristic size property is assumed to be mathematically additive: this is essential to ensure that size is conserved through the pile.

Modelling of material flow and size distribution of ore in a stockpile …
This study aims to understand the material behaviour of ore inside a coarse ore stockpile by discrete element modelling. This is of importance since the stockpile is the last stage to control the size distribution of ore in the ore handling system before feeding the grinding circuit. An optimal size distribution is required for efficient grinding in an autogenous grinding (AG) mill.

Wear lining for coarse ore stockpile hoppers
Accurately predicting when to change liners in COS (coarse ore stockpile) feeder hoppers can be problematic. Running down the stockpile to take 3D scans is expensive and disruptive. External ultrasonic thickness testing of the liners may be possible but often gives false information if composite materials (such as weld overlay) are being used.

2) What recovery factor should be used for fresh stockpile? Should it be the same as for run of mill ore? Most planners use the same number. 3) Is the stockpile grade tested or is is just a mathematical calculation at month end reconciliation? If the latter then you may get an unpleasant surprise when it comes time to mill the stockpile.
