Reconciliation 8 May 2018 5 "Bite-sized Chunks" •Reduce reconciliation to a series of depletions in model tonnages, grades and metal content. Often expressed as factors (Parker, 2012) •F1 factor usually relates short term (grade control) model to ore reserves depleted •F2 factor usually relates received at mill (measured by the mill) to

Engineering Mining Technology Abstract 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.

The ball mill is usually the largest energy consumer at a mine site and significantly affects operational expenditures. Given a target particle size, Bond Mill Work Index estimates are used to predict a ball mill's throughput. In order to maximize ball mill throughput and optimize energy utilization, it is important to get these estimates right.

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 through risk mitigation and embedding optimization opportunities.

Proactive reconciliation was developed for detecting the causes of reconciliation problems at each process stage and can be used as a tool for integrating mining and milling operations in an effective and reliable way, as presented by Morley [9] and Chieregati and Pignatari [12]. Following the authors' recommendations, the reconciliation ...

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 indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.

dilution on the profitability of mining operations. More specifically, in 2008, Stewart and Trueman (2008) reported that unplanned dilution costs A$25 per ton, compared with A$7 per ton for mucking and haulage, and A$18 per ton for milling in typical narrow-vein longhole stoping operations. Suglo and Opoku (2012) conducted a study on Kazansi Mine

1. Reconciliation between the mine and mill production should be done on a regular basis but monitored on a daily basis to ensure accuracy of sampling and record keeping. Current best practice is considered to be reconciliation on a monthly basis. 2. A reconciliation provides checks for discrepancies, which may require changes to operational ...

Milling is the process of crushing, grinding, and treating of raw material from the mine to extract a saleable product. It also involves the processes of hoisting and transporting of broken ore to the mill via trucks or conveyor belts. This is an approach to reconcile the blasted material at the stope face with the hoisted raw material at the ...
