(Springer, 2020)Mine planning optimization aims at maximizing the profit obtained from extracting valuable ore. Beyond its theoretical complexity-the open-pit mining problem with capacity constraints reduces to a knapsack problem with ...
-
(Elsevier, 2015)The Geostatistical Software Library (GSLIB) has been used in the geostatistical community for more than thirty years. It was designed as a bundle of sequential Fortran codes, and today it is still in use by many practitioners ...
-
(Elsevier Ltd, 2018)Traditional practice in mine planning often relies on estimation techniques that fail to account for the intrinsicuncertainty of geology and grades, which may have significant consequences in the mine operation. Dealing ...
-
(Springer, 2020)A weighted compressed sensing (WCS) algorithm is proposed for the problem of channelizetl facies reconstruction from pixel-based measurements. This strategy integrates information from: (i) image structure in a transform ...
-
(Springer, 2020)Integration of renewable energy into mining and processing operations is becoming necessary as part of a strategy towards sustainability in the minerals industry. A solar photovoltaic plant along with a battery energy ...
-
(Springer, 2020)Grade control and short-term planning determine the performance of a mining project. Improving this decision, by collecting the most informative samples (data) may have significant financial impact on the project. In this ...
-
(Elsevier Science BV., 2016)The uncertainty in the recoverable tonnages and grades in a mineral deposit is a key factor in the decision-making process of a mining project. Currently, the most prevalent approach to model the uncertainty in the spatial ...
-
(Springer Verlag, 2019)© 2019, International Association for Mathematical Geosciences.The task of optimal sampling for the statistical simulation of a discrete random field is addressed from the perspective of minimizing the posterior uncertainty ...
-
(Springer, 2020)The access to real geometallurgical data is very limited in practice, making it difficult for practitioners, researchers and students to test methods, models and reproduce results in the field of geometallurgy. The aim of ...
-
(Elsevier, 2015)An accurate definition of geological domains that differentiate the types of mineralogy, alteration and lithology is a critical step in mineral resources and ore reserves evaluation. Deterministic models define just one ...
-
(Elsevier Ltd, 2019)In the first part of this work, a solar photovoltaic system with battery storage (PV-BESS) and grid backup system to supply a SAG mill was modeled. There, the overall framework, the optimization model, and the model for ...
-
(Elsevier, 2014)One of the main difficulties using multi-point statistical (MPS) simulation based on annealing techniques or genetic algorithms concerns the excessive amount of time and memory that must be spent in order to achieve ...
-
(Universidad de Valparaíso, 2015)The chain of islands including Desertores, Apiao and Quemchi located in the Inner Sea of Chiloé, in northern Chilean Patagonia (41°- 44°S), acts as a natural barrier for the flux of water in the north-south direction, ...
