Reconciliation is a common activity carried out at most mining operations around the world and can be defined as a comparison between the grade reported by the plant and the grade predicted by models. Of course these values rarely match, due to the different variables involved. The mine/mill reconciliation problem often has multiple causes.
The current mine to mill reconciliation at Iduapriem mine compares production estimates from various sources (resource model, grade control model, pit design, plant and stockpile, truck tally, stock pile and plant feed, plant feed, and plant received) over a defined period.

Several years of favourable Mine to Mill reconciliation data from the mining and processing of higher grade and lower grade stockwork styles of gold mineralisation provided the confidence in the approach to grade control to support the expansion plans during a period of low gold prices.
Jun 20, 2017· Over the years the mine and the plant developed a fantastic working relationship and through a lot of hard work, robust practices and open communication they came to understand each other, consequently the monthly and annual mine-to-mill reconciliation was always very close.
English term or phrase: mine-mill reconciliation: Bonjour à toutes et à tous ! Je traduis un document minier en Afrique aux allures de bilan par trimestre urgent. "Operating Strategy Continue ***mine-mill reconciliation*** testing Execution of groundwater strategy Successful implementation of geomechanical (GMX) monitoring technology"
An opportunity for improvement presents itself in the area of mine-mill reconciliation, which entails the quantification of the variance between measurement points along the mining value chain. Reconciliation factors are calculated from the variance between respective sections within the mining sequence.
Finally, mine-mill metal accounting and reconciliation systems need a procedure for on-going evaluation, where historical trends are continuously examined over time and where issues highlighted over one or more accounting periods are investigated and corrected.
Several years of favourable Mine to Mill reconciliation data from the mining and processing of higher grade and lower grade stockwork styles of gold mineralisation provided the confidence in the approach to grade control to support the expansion plans during a period of low gold prices.The paper is intended to complement the discussion of ...
The Advanced Mine to Mill concept recognised these limitations and developed practical strategies to address them. A brief list of some of these strategies is given below: Produce optimum size distribution (not just finer) and balancing the transfer size between the SAG and ball mill to improve the overall circuit throughput (Powell et.al 2018).
Mine reconciliation is the practice of comparing the tonnage and grade of material processed by the mill with the tonnage and grade of ore in the reserve model of a deposit, and with the tonnage ...
from a history of favourable mine to mill reconciliation data when planning operational expansions. Case study 1 – The Damang Gold Mine: Ghana The following narrative is a summary of the ...
improvement in mill throughputs and better mine to mill reconciliation indicating lower dilution levels (Gaunt et al. 2015, Kanchibotla 2013, Rogers and Kanchibotla 2013, Engmann et al. 2012). A general perception of mill optimization is simply increasing blasting energy to produce finer
Mar 01, 2019· Good reconciliation between the mine and the mill (MR = 90%). This example demonstrates that successful reconciliation is based on the integration of geology, mining and milling operations. Even though plant recoveries were kept low after process changes, the improvements in reconciliation results show that proactive reconciliation is an ...

The F2 factor usually relates received at mill (measured by the mill) tonnages, grades and metal content to delivered to mill production tonnages, grade and metal content. The F3 factor is F1×F2 and enables a comparison of a mine's (measured by mine) ability to recover the tonnage, grade and metal content estimated in ore reserves.
