Abstract

Mines classify their resource as ore or waste in various manners. A common approach is to apply a cut-off grade. How this cut-off grade is optimised, has been extensively researched and there are thousands of academic papers covering this topic in the public domain. The question for this paper is if mines are actually considering these various techniques in practice. The background to this research paper is the MSc (Mineral Resource Management) at University of Witwatersrand student assignments where this has been a topic for 2014, 2015, 2016 and 2017. The focus of the students’ research is: “Is it ore or is it waste?”. This question was posed to the students to research it on their operations where they are employed.
