• By process (short range to long range model, mill to mine production) A combination of the above methods may provide the best fit for an operation. Any reconciliation program is recommended to be based upon clear concise goals. Reconciliation methods should be specifically adapted to handle the unique problems that occur at each operation.
begin to plan for the development of the mine. This phase of the mining project has several distinct components. 1.1.2.1 Construction of access roads The construction of access roads, either to provide heavy equipment and supplies to the mine site or to ship out processed metals and ores, can have substantial environmental impacts,
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 …
Kupol mine is located in the Far East of Russia within the Chukotka Autonomous Okrug (Chukotka A.O.). The mine is approximately 220 km (by air) southeast of the town of Bilibino and 430 km northwest of the town of Anadyr. The Kupol property covers 1,767 ha, with adjacent license areas Kupol West, Kupol East, Kupol North and Levo-Mechkereva.

The first objective of "Mine to Mill" blasting is to reduce the top size of the material to improve the ease of excavation and transport within the mine. Reduced top size also allows the primary crusher gap to be reduced, generating material which needs less breakage in the mill. With reduced top size and continuous material
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.

A definite consequence of the former is the haulage of misclassified ore to waste dumps or waste to the mill. 5. Practical and Theoretical Approaches to Reconciliation. Years of practice have yielded various means of conducting ore grade reconciliation in a typical mine. The variety of techniques to reconciliation include [4, 6, 9, 10]: i.
mation is made useful and functional. In the mine environ-ment, sensors and instrumentation are rationalized in a man-ner so as to generate minimum levels of data redundancy. This enables mathematical improvement of data (supported by mass conservation equations). Data reconciliation via this means (mass balancing) improves accuracy of process and

Fluctuations in periodic reconciliations between the mine and the mill are an expected and common experience in mining and processing operations. These fluctuations are caused in part by errors in the estimates of tonnage and grade of the mined material as well as errors in the mill's assessment of the material processed. Keeping these errors small and unbiased is an important aspect of an ...
