Optimizing the life of ore passes in a deep-level gold mine
Main ore pass systems should last the life of a mine, and too often expensive and hazardous remedial measures are required to repair a damaged ore pass in an attempt to extend its life. In order to maximize the life expectancy of all ore passes at Moab Khotsong, 'wearing blocks' and 'softer support' systems, combined with basic
Distinguishing the Type of Ore-Forming Fluids in Gold
Pyrite geochemistry is crucial for the discrimination of the types of ore-forming fluids in gold deposits, such as metamorphic–hydrothermal fluids and magmatic–hydrothermal fluids. With the assistance of supervised machine learning algorithms, this application can be leveraged maximally. Here, laser ablation inductively …
