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

Comparison of golden section search method and imperialist competitive algorithm for optimization cut-off grade- case study: Mine No. 1 of Golgohar

S. Mohammadi; M. Ataei; R. Khalokakaei; E. Pourzamani

Volume 6, Issue 1 , January 2015, , Pages 63-71

https://doi.org/10.22044/jme.2015.364

Abstract
  Optimization of the exploitation operation is one of the most important issues facing the mining engineers. Since several technical and economic parameters depend on the cut-off grade, optimization of this parameter is of particular importance. The aim of this optimization is to maximize the net present ...  Read More

The effect of price changes on optimum cut-off grade of different open-pit mines

Ali Asghar khodaiari; A Jafarnejad

Volume 3, Issue 1 , January 2012, , Pages 61-68

https://doi.org/10.22044/jme.2012.75

Abstract
  Maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. When this is the case, the price of the product has a critical effect on optimum value of cut-off grade. This paper investigates the relationship between optimum cut-off grade and price to ...  Read More
