For a mining operation, minimizing misclassification of ore and waste during grade control is of critical importance. This paper reviews grade control procedures for classifying ore and waste …
Strong production is expected to continue into 2025-2027 with higher ore grade and throughput from treating Lornex material during this period. Our share (22.5%) of copper production at …
conducting ore grade reconciliation in a typical mine. The variety of techniques to reconciliation include [4,6,9,10]: i. Depletion by mining; ii. Reconciliation of resources with grade control; iii. …
Ore-control procedures are designed to allow mining of several ore types simultaneously but enabling one type to be sent to the concentrator at a time in order to …
One of the advantages of the F3 metric is that it removes the effect of ore control sampling (grade) bias, which often afflicts ore control. ... For example at Antamina Mine in Peru, a factor F1' was developed that compared …
The JK Value-Based Ore Control (JKVBOC) software uses numerical modelling to simulate and predict the blast-induced 3D displacement of blasted material including the ore/waste boundaries so that ore loss and dilution can be …
Antamina is a polymetallic skarn orebody with a regional structural trend parallel to the Andean Cordillera Trend. Major geological faulting and associated jointing was intruded by a multi-phased quartz-monzonite porphyry about 9.8Ma, resulting in a large area of intrusives …
The grade control (or ore control) process involves the predictive delineation of the tonnes and grade of ore that will be recovered by mining. The predictions have a number of common …
As of January 2010, proven reserves at Antamina stand at 100Mt graded at 1.14% copper, 0.17% zinc, 8.7g/t silver and 0.036% molybdenum. Proven reserves of copper-zinc ore are 42Mt …
grade control defined dig block grade is reported i.e. no factors applied. There is always going to be ore loss and dilution during the normal mining process, therefore the reporting of mined …
Ore classification at Antamina considers six principal ore types which are processed based on grinding and flotation requirements. One of these ore types includes sub categories, M4 and …
Antamina's Mine to Mill Throughput Improvement Ed Rybinski November 2012 Based on Paper "Optimization and Continuous Improvement of …
The JK Value-Based Ore Control (JKVBOC) software uses numerical modelling to simulate and predict the blast-induced 3D displacement of blasted material including the ore/waste …

(Fig. 1), are situated proximal to Antamina. Figure 1: Location Map of the Antamina Mine Regional Geology The Antamina deposit is located in the Andes mountain belt, which is situated on the …
The Antamina deposit is hosted by calcic skarn alteration, related to a low grade to sub-economic Miocene calc-alkaline porphyry copper-molybdenum mineralised intrusion.
The life-of-mine plan was optimized using variable cut-off grades; so there is not a single cut-off grade applied to the reserve estimate. (4) The information in this press release …
Ore-control procedures are designed to allow mining of several ore types simultaneously but enabling one type to be sent to the concentrator at a time in order to …

Antamina is currently implementing a system to track ore movements from the shovel face to the concentrator. Relatively sophisticated models of the ROM and coarse ore …
Optimizing Grade Control: A Detailed Case Study Mario E. Rossi GeoSystems International Abstract The most important task in daily life of an open-pit mining operation is to perform in …

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 …
Grade control is a fundamental activity for Short-Term Mine Planning as it validates the ore-waste and ore type classification of mine faces. Geological mapping and …
Saat mining ore, grade control harus melakukan pengawasan agar: Tidak terjadi over cut, di mana bedrock/bluezone material ikut tertambang (dilusi dari material blue zone). …
