Modelling Stockpiles In A Mining Project

Financial Modelling of Stockpiles in a Mining Project

Modelling stockpiles is a crucial component of a financial model in a mining project, because most likely mining companies are not able to mill all the ore that they mine. Further, this stockpile of contained metal has a monetary value which needs to be reflected on the balance sheet.

Linear models for stockpiling in open-pit mine production

Jul 01, 2017 Common models assume that material in these stockpiles, or “buckets,” is theoretically immediately mixed and becomes homogeneous. We consider stockpiles as part of our open pit mine scheduling strategy, propose multiple models to solve the OPMPS problem, and compare the solution quality and tractability of these linear-integer and nonlinear

Linear models for stockpiling in open-pit mine production

We propose new linear models for modeling stockpiles in open pit mining. • We compare how their assumptions affect solution quality and tractability. • These models include blending requirements without unrealistic assumptions. • Experiments show that our proposed models

3D Stockpile Modelling to Improve the Quality Control in

Currently, stockpiles are modelled mathematically or geometrically in most stockpile management systems. With mathematic models, it is assumed that the quality composition is known mining sites. With geometric models, most of them are based on the ideal geometric shape of a stockpile or without ability to update the model in real-time. In a

Mine stockpile design to minimise environmental impact

Keywords: quality control, decision support, mining, stockpile design, intelligent stacking/reclaiming, forecasting, simulation. 1 Introduction Iron ore from inland mines is railed to port, where it is crushed, separated into lump and fines products and stored onto large stockpiles. Ships are loaded for export with ore reclaimed from the

Numerical modelling of the MILP formulation for open pit

Dimitrakopoulos, 2004; Dagdelen and Kawahata, 2007). The MILP models theoretically have the capability to consider diverse mining constraints such as multiple ore processors, multiple material stockpiles, and blending strategies. The applications of MILP models result in production schedules generating near theoretical optimal net present
