Simultaneous Optimization of Mine Production Rate and Cut-off Grade Using Particle Swarm Optimization

Javad Lotfi Godarzi; Ahmad Reza Sayadi; Amin Mousavi; Micah Nehring

Articles in Press, Accepted Manuscript, Available Online from 24 November 2024

https://doi.org/10.22044/jme.2024.13943.2601

Abstract
  The production rate and cut-off grade are two critical variables in the design and planning of open-pit mines. Generally, the production rate depends on the reserve amount, which is influenced by the cut-off grade. Additionally, the cut-off grade is affected by the production cost, which is influenced ...  Read More

Optimizing Long-Term Production Scheduling in Open Pit Mining under Commodity Price Uncertainty: A Two-Stage Stochastic Programming Approach

Elham Lotfi; Javad Gholamnejad; Mehdi Najafi; Mohammad Sadegh Zamani

Volume 15, Issue 4 , October 2024, , Pages 1491-1508

https://doi.org/10.22044/jme.2024.13814.2576

Abstract
  In the context of open pit mining operations, long-term production scheduling faces significant challenges due to inherent uncertainties, particularly in commodity prices. Traditional mathematical models often adopt a single-point estimation strategy for commodity price, leading to suboptimal mine plans ...  Read More

UPL determination of multi-element deposits with grade uncertainty using a new block economic value calculation approach

M. Jamshidi; M. Osanloo

Volume 9, Issue 1 , January 2018, , Pages 61-72

https://doi.org/10.22044/jme.2017.5763.1387

Abstract
  The block economic value (BEV) of a single-metal deposit is calculated based on the metal content and the related costs. The common methods available for calculating BEV are just based upon the profitable elements, and the effects of undesirable elements on BEV are not considered. However, in multi-element ...  Read More
