A Review of Alternative Procedures to the Bond Ball Mill Standard Grindability Test
(Metals, 2021)
A lo largo de los años, se han propuesto procedimientos alternativos a la prueba de molienda Bond. Con el objetivo de evitar la necesidad del molino estándar o reducir y simplificar el procedimiento de molienda. Algunos ...
Using advanced mineral characterisation techniques to estimate grinding media consumption at laboratory scale
(Elsevier, 2018-06)
Grinding media is very important in the mineral processing, mainly because its consumption involves significant costs of grinding and consequently, of the total mining operational expenditure. During grinding, chemical and ...

Evaluación de las propiedades fisicoquímicas y petrográficas y su influencia en la molturabilidad de los carbones del Sinclinal Checua-Lenguazaque
(Universidad Pedagógica y Tecnológica de ColombiaEscuela de Ingeniería GeológicaFacultad Seccional Sogamoso, 2018)
La presente investigación aporta información del comportamiento de la molturabilidad de los carbones influenciado por los análisis petrográficos y fisicoquímicos del sinclinal Checua-Lenguazaque en los bloques Sutatausa, ...
Simulation of Synthetic Exploration and Geometallurgical Database of Porphyry Copper Deposits for Educational Purposes
(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 ...
Thermal analysis to assess pozzolanic activity of calcined kaolinitic clays
(Springer, 2014-04)
The use of calcined clays as partial replacement of cement is encouraged since it promotes the reduction of the green-house gas emission and the energy requirement of cement-based material, maintaining or enhancing the ...
Calcined illite-chlorite shale as supplementary cementing material: Thermal treatment, grinding, color and pozzolanic activity
(Elsevier Science, 2019-10)
The thermal transformation (100–1100 °C) of two shales containing illite-chlorite (I/Ch), feldspars and quartz from La Cabañita quarry (Olavarria, Argentine) was studied by TG-DTA, XRD and FTIR. It included dehydration; ...
Effect of temperature during wood torrefaction on the formation of lignin liquid intermediates
(ELSEVIER, 2014-09-01)
Torrefaction enhances physical properties of lignocellulosic biomass and improves its grindability. Energy densification, via fuel pellets production, is one of the most promising uses of torrefaction. Lignin contributes ...
