Proactive reconciliation as a tool for integrating mining ...

01/03/2019  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 effective tool for the company to

13/12/2017  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. The F1 factor measures the accuracy of orebody knowledge

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. These factors are commonly used as key performance indicators to provide a check on the ...

The challenge of sampling gold - SAIMM

The mine/mill reconciliation problem often has multiple causes. But the problem can be solved, or at least minimized, if a good strategy is undertaken. Pitard4 suggests dividing the complex problem into its basic components, and then solving them one at a time. These components are presented in Table I. The following items discuss some problems observed on both gold deposits under study, and ...

Reconciliation - Optiro

Reconciliation of resource and reserve models, grade control models, mine production data and plant tonnage and grade is one of the most vital functions in the mining cycle. Not only does it serve to validate (or not!) the Mineral Resources and Ore Reserves, the reconciliation can highlight any issues in the reserve to production process and in the ore tracking and stockpiling systems. However ...

The Reconciliation Myth #4 – “The Day-2 Conundrum”

04/07/2017  As I discussed in “The Reconciliation Myth #1” there’s an understandable but naïve desire to have the mine and mill tonnes and grade match, be it over a day, a week, a month, a quarter or a year. This ‘everything must balance’ logic is, in my opinion, driven by an accounting mindset. I’ve gone so far as to call the end-of-month process ‘ore accounting’ instead of ...
