Mechanochemical sulfidization of a mixed oxide-sulphide copper ore
Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency Considering the continuous increase in production costs and resource optimization, more than a strategic objective has become imperative in the copper mining industry. In the search to improve the efficiency in the use of resources, the present work develops models of a semi-autogenous grinding (SAG) mill using statistical analysis and Materials Free Full-Text Optimization of the SAG Grinding

Inside a mining company’s AI transformation McKinsey
The mood was apprehensive as data scientists, metallurgists, and engineers from Freeport-McMoRan filed into the control room of a copper-ore concentrating mill in Bagdad, Arizona, on the morning of October 19, 2018. They had come to learn what would happen when they cranked the big mill up to a work rate that had never been tried. The grinding conditions affect significantly the subsequent flotation stage of this sulphide copper ore. The presence of iron ions in the slurry is deleterious to the flotation of copper minerals and may be avoided by the utilisation of lined mills and non-ferrous or corrosion resistant grinding media, such as stainless steel or pebbles.The effect of grinding conditions on the flotation of a sulphide copper ore

Optimization of the SAG Grinding Process Using Statistical
2. Background. The SAG grinding process has been modeled by various authors, either generating explanatory models of the grinding process, with the aim of modeling, simulating, and optimizing the individual process, as well as integrating it into aggregate processes, such as the mine-to-mill (M2M) paradigm, a practice that has The results show that grinding time is a significant factor affecting the particle size composition. The suitable grinding concentration of Tongkeng ore and Gaofeng ore is 70% and 75%, respectively. The effect of mill filling ratio on Gaofeng ore is not obvious. The rotational rate has little effect on the grinding technical efficiency.Special Issue "Grinding Modeling and Energy Efficiency in Ore
