Due to tighter financial margins, the need for better knowledge of grade data is required. Geological models allow the user to have a better understanding of the geological environment in which mining is taking place. Three ...

Gem garnet chemistry is described using the end-members pyrope, almandine, spessartine, andradite, grossular, and uvarovite. The large variation in garnets makes classification difficult. Garnet gemstones are typically ...

Platinum-group elements (pGEs) are recovered from UG2 chromitite by milling and flotation. The mechanisms involved during beneficiation of this type of ore are still poorly understood, partly because of its complex nature. ...

At the Karee Mine of the Lonplats mining company in the Bushveld Complex, South Africa, the Rooikoppies iron-rich ultramafic pegmatite (IRUP), which covers the stratigraphy from below the UG2 chromitite layer up to the ...

This study presents a detailed petrological and geochemical investigation of the concordant ultramafic pegmatites of the Lower Critical Zone at Dwarsrivier Mine, in the eastern Bushveld Complex. The pegmatites are ...

Traditional float and sink analyses are undertaken to determine the washability of coal. Float and sink analyses are costly, require toxic heavy organic liquids and the procedure to wash and dry the float and discard ...

Very limited studies have been conducted on titaniferous-magnetite exsolution textures and the conditions needed for the formation of these textures. Published research surrounding the exsolution textures consider only ...
