Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.

This paper aims to present the concept for a novel gapcalibrated methodology that was developed to predict the operating gap by calibrating the piston press compressed bed thickness with the HPGR operational gap. On average, less than ±% prediction errors have been obtained for the HPGR operating gap when validating using iron and copper ore.
