Threedimensional textural investigation of sulfide ...
Overall, sulfide grain sphericity is dependent on sulfide diameter: it increases with decreasing grain size. The sphericity of sulfides in the Loolekop Pipe ranges from to, but can reach in some samples (Figs 8c, 9c and 10c). A sphericity of less than is typical of sulfide cumulates and corresponds to a sulfide diameter ......
Rebellious Ores: Sulfides, Selenides and Tellurides
Rebellious Ores: Sulfides, Selenides and Tellurides. The early day miners feared it, and it happened a lot more often than they would have liked: the easily worked rich surface ores they discovered on the surface gave way as they mined downward, to a vein full of sulfides, base metals and other nasty, rebellious and refractory ores....
