Longitudinal Storage
Systems for stockpiling, removal and reclaiming, covered storage systems and blending beds for homogenisation of raw materials Longitudinal stockpiles are very often created where there is a necessity to store large volumes of bulk materials in between individual stages of a process.

3D stockpile modelling and quality calculation for continuous stockpile
To create a custom required specification, a stockpile needs to mix a number of raw materials with different chemical properties in time and in order. This process is called blending. In practice, the blending operation is achieved through two intricately connected operations: grade targeting and stockpiling.

Linear models for stockpiling in open-pit mine
Smith and Wicks (2014) use a mixed-integer program (MIP) that maximizes recovered copper and accounts for constraints on shovel, extraction, stockpiling, and processing capacities, as well as blending. Here, the stockpiling constraints result in an optimistic bound on the model, in that each block is retrieved from the stockpile having ...
