Re: Stockpiles
The advantages/disadvantages of circular/longitudinal blending beds are associated with the space available to install the blending bed. When space is tight then a circular bed takes up less space. However, I suspect circular beds are more expensive. The simplest blending effect is just the standard deviation onto the pile divided by the standard deviation of material reclaimed from the pile. For limestone the criteria might be CaO (or CaCO3), SiO2, MgO dependent on which was critical. For coal ash content would probably be best.

Re: Stockpiles
In a longitudenal stockpile it is not possible to have a continous pile and material at the ends tends of a different composition as fine and coarse material tend to get separated and coarse particles rolls on the ends.
This problem can be there in circular stock pile also if seprate piles are formed.
Also circular stock piles can not be of high capacity.
