The geometallurgical model is a tool that allows evaluating the necessity of mineral deposits from the geological, processing and production point of view. With this, it is possible to estimate the most realistic net present value and significantly reduce the technical-operational risk that occurs in the feasibility stages of a mining project. In the present investigation, an exhaustive search has been carried out on studies focused on geometallurgical modeling in porphyry copper deposits in which it has been estimated and simulated as geometallurgical total copper grade, oxide copper, penalizing elements, metallurgical recovery, bond work index and of abrasion. Through this research, it is evident that by incorporating geometallurgical attributes in the estimation of mineral resources, it is possible to better quantify the spatial variability of the deposit, anticipate those minerals th...

The ore deposits in Ecuador are associated with narrow veins whose rock host is influenced by joints and stress that are sources of weakness, which needs to be studied for safe underground exploitation. Therefore, the objective of this research is to elaborate the geotechnical design for the underground mining stope in a narrow vein. For this purpose, the rocky massif was characterized using geomechanical classifications and its stability by means of Mathews' Graph. In addition, stress field, displacements and strength factor were examined using the failure criterion and RS2 software; additionally, the support was designed based on the quality of the rock mass and the mining method’s sequence. The results indicate that the maximum size of the stope is 54.00 m height, 1.75 m width, 79.00 m length; and, the designed support has stabilized the drifts. Also the results reveal that joints c...

La industria minera afronta desafíos asociados a la incertidumbre geológica y de procesamiento en los depósitos a causa de la variabilidad en sus atributos geometalúrgicos, lo que afecta notablemente la etapa de exploración e incrementa el riesgo de un proyecto minero. Por lo tanto, se elaboró un modelo geometalúrgico para optimizar la estimación de recursos minerales en depósitos tipo pórfidos cupríferos, considerando como variables primarias la litología, zonas de mineralización, ley de cobre total “CuT”, resistencia a la compresión uniaxial de la roca “UCS” y como variable de respuesta el índice de trabajo del molino de bolas de Bond “BWi” de un depósito ubicado en Perú; cuyo análisis e interpretación se realizó en los software Jupyter Notebook, RecMin y SGeMS. El desarrollo de la estimación consistió en análisis exploratorio de datos, definición de...
