In an open pit mining operation, the heterogeneity of the grade-tonnage distribution of the
deposit dictates that all available material within the boundaries of an open pit may not be …

The geotechnical behavior of a mixture of kaolinite and vinyl polymers with different
monomer types was investigated using a series of laboratory tests. Three polymers were …

Optimum cut-off grades with different types of objective functions are determined by
optimization algorithms which recognized as the one of the basis of sustainable …

An integral connection exists among the mine production planning, the mined material
destination, and the ultimate pit limit (UPL) in the mining engineering economy. This relation …

The optimal cutoff grade leads to maximizing the profit or the net present value (NPV). One
of the most important issues in open pit mining is cutoff grade optimization with regard to …

The physical and mechanical behavior of soil polymer composites tightly depends on the
properties and structures of both soil and polymer. This study aims to investigate the effect of …

Determining the final destination of mined materials is counted as one of the most important
challenges in mining. Cut-off grade is a criterion specifying the destination of mined …

Determining the hydrometallurgical cut-off grades specifies the destination of low grade
materials and this is subjected to more benefits in mining. Copper production rate is …

Cut-off grade is one of the important aspects of mining engineering. It distinguishes which
material is worth mining and processing or stockpiling and which one should be left or …

This study presents a new mathematical model for cut-off grade and production scheduling
optimisation in open pit mining operations. The model maximises the net present value of …
