mining reconciliation

 · 1. Introduction Reconciliation is carried out by most of the world''s mining companies and is based on the calculation of the so-called "mine call factor" (MCF). The MCF represents the ratio between the grade, contained metal or mass of produced ore with the grade ...

Our team of mining consultants have reconciliation capabilities associated with open cut and underground bulk minerals, industrial minerals, precious metals and base metals projects. We have worldwide experience with resource and reserve evaluation, grade control systems, short and long term mine planning and scheduling, underground thin vein ...

Reconciliation will increasingly become the benchmark by which mining company performance is judged, based on comparing actual production with predictions (promises). This paper outlines the objectives, principles, processes and practice of a robust reconciliation program. Reconciling from the resource through to delivery of a mineral product is the key to adding value during development of a mining …

What is Mine Reconciliation? Comparison of estimated tonnage, grade and metal with actual measurements. Aims to measure the performance of the operation. Supports …

Temporal (or ―time based‖) reconciliation is the most common form of reconciliation. Temporal reconciliation compares performance across the mining sequence on time based ranges (such as shifts, days, weeks, months, years etc). It does not necessarily compare information from a spatial perspective, which may vary over the short term, but relies on the fact that these geographical discrepancies ―smooth out‖ over longer periods of time, normally months or years. Temporal reconciliation allows tracking of data over time, typically monthly or yearly. Temporal reconciliation …

Coal Reconciliation (Open-cut Mine Surveying Duties) The reconciliation process involves determining how much coal has been mined. It allows the company to determine whether the amount of coal being delivered matches the amount of coal coming out of the pits, as well as allowing various geological tasks to be completed.

Reconciliation involves the collection of tonnage, grade (quality) and contained metal (product) data from disparate and hopefully independent sources. Examples are exploration data, production...

The elements that should be incorporated into a mine''s reconciliation code of practice include: • Key reconciliation relationships • Data collection and validation definitions • Methodologies and...

Mine Geology, Grade Control, and Reconciliation Optimize mine planning and profitability by understanding the geological controls on orebodies An appreciation of the geological spatial controls to mineralization is fundamental to mine operation optimization, near-mine exploration, resource estimation, geotechnical engineering, and mineral processing.

 · The F-Factors, or F-Series metrics, are the closest thing we have to a ''standard'' for reconciliation. They were first proposed and described by Harry Parker in 2006 and have been adopted to various degrees and in various ways by most of the major minerals companies.

 · Reconciliation involves the collection of tonnage, grade (quality) and contained metal (product) data from disparate and hopefully independent sources. Examples are exploration data, production sampling data from blast holes or draw points, and process plant data. These data may be compared by means of ratios (factors).

 · This article was written by Snowden''s Mining Consulting Manager, Geoff Booth. As part of a retrospective over a somewhat disparate reconciliation career, including time in the oil patch as a refinery economist and multiple front-line operational roles for base and precious metal miners, I''d thought a reflective commentary on some of the bigger reconciliation bugbears I''ve […]

Reconciliation of the recovered resource is an important instrument for assessing the performance of sublevel caving mines. While the quality of reconciliation has improved significantly the method requires a significant period of production history in excess of 18 months before valid local conditions can be incorporated in recovery estimates. The introduction of computer models which …

Mine-to-mill reconciliation is a crucial function to understanding value and performance within a mine operation. By comparing actual results against estimates and assumptions, you can calibrate a mine plan and continuously improve it by delivering higher value …

The reconciliation of an entire stope volume is systematically performed at most open stope mines and is often complimented by the reconciliation by individual stope faces. The octree analysis is a novel stope reconciliation technique that subdivides stope volumes into small blocks (usually <1 m).

Physical reconciliation is concerned with attributes such as contained metal, various quality parameters and volumes. It is characteristic of mining companies to combine physical reconciliation with temporal data, the report of which is usually done over long time periods (quarterly or annually).

Reconciliation should be an implicit part of the mining process, and reconciliation targets should be a key performance indicator for well run mines. Abstract Reconciliation involves the collection of tonnage, grade (quality) and contained metal (product) data from disparate and hopefully independent sources.
