The influence of copper ore lithology on the grinding media wear

The paper presents results of investigations aimed to find relationship between grinding media wear rate and lithology of ores processed in copper production. Laboratory wear tests of grinding media were carried out for “pure” lithological components, natural copper ores and artificial mixtures prep...

Description
Summary:The paper presents results of investigations aimed to find relationship between grinding media wear rate and lithology of ores processed in copper production. Laboratory wear tests of grinding media were carried out for “pure” lithological components, natural copper ores and artificial mixtures prepared in the laboratory. Test samples were characterized in terms of lithology, and the results were used for interpretation of results of grinding media consumption. Based on the laboratory tests results a new wear function of grinding media consumption related to lithology of ores was established. •Wear rate of grinding media is variable function of ore components.•The largest share in the grinding media wear indicates sandstone ore.•Developed function describes relationship between ore lithology and grinding media consumption.•Results can be used to predict wear rate of grinding media during copper ores processing.
