Conference Proceedings - World Mining Congress 2026

2030 Between 1996 and 2002, the collaborative research project “Fragmentation optimization for downstream processing,” developed by the Julius Krutschnitt Mineral Research Centre (JKMRC) in Queensland, Australia, sought to improve mining and mineral processing activities through the use of mathematical modeling and simulation for different stages of the mineral production chain (Cameron et al., 2017). The technology developed in this project became globally known as “Mine to Mill.” McKee (2013) presents a history of this integrated study from blasting to grinding, including concepts and case studies from the project. Subsequently, emerging technologies enabled further refinement of the technique, such as image analysis, simulation software, ore-tracking devices, etc. Adel et al. (2006) proposed adapting the technology developed by the JKMRC for application in the aggregates industry, applying the models to two quarries in the United States. Valery et al. (2007) presented a methodology developed for this integration among different stages and reported significant gains from its application, generally between 5 and 20%. Mahmoud (2013) developed an integrated model for optimizing the production process, from mining to the processing plant. 2. INNOVATIVE MINE TO CRUSCHER MODEL 2.1 Mine to crusher cost minimization model At ITV/Vale S.A., research studies related to this topic have been carried out since 2017, presented through Equations (1) to (5) and figure 1 (Navarro Torres V.F. et al., 2017 to 2024 and Navarro Torres V.F. et al., 2022). %&,D>K& = '%&, +%D +%> + %K&(+c (1) %&, =)ç$?(è?ê)?ë'B$'B?$C%í ì( *+#,Z#&#á( åD9 , !,#- ;s ! î ! .  ë'B.<,T (2) %D =$Eï529,9;GHI?#(<,!!ZA?<,Tñ!)?>E=ó ZÇ<<JENE (3) %> =$!ïïçñ,Z<Y}29,9#DJD9?#>%?>=í⁄Ç<ó&?(>)?>=?>'íó Ç<J!N!
