Using meaningful reconciliation information to evaluate

Jan 01, 2000 · Reconciliation of production information is critical to evaluating the effectiveness of predictive models that would allow for the optimization of mining operations. Whether mining open pit or underground, minetomill reconciliations can be one of management''s better tools for the performance of proper accounting.

Proactive reconciliation as a tool for integrating mining

Crawford proposed a complete reconciliation flowscheme where each step of the operation is examined sequentially from model to mine, mine to mill, mill to smelter or refiner or to final sales, showing that reconciliation can be used as a powerful tool for determining if a production problem exists at an operation, and often provides diagnostics

How can a systemic approach improve the Mine to Mill Reconciliation process? The research begins with the Critical Realist philosophy that searches for the generative mechanisms, which that operate at a deeper level than the superficial constant conjunctures. At this stage nobody really knows what is causing the lower than expected grades.

Mine to Mill teck

"Sitebased mine to mill optimization initiatives usually begin by looking for ways the mine and the mill can work better together, making sure both are operating as effectively as possible. Typically, mine to mill optimization means expending more energy at the mine level, so that once ore gets to the mill it requires less energy to process

Ore Grade Reconciliation Techniques – A Review

The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indiion that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.
