Is sphalerite a mineral or a rock
granular sphalerite, galena and barite are typical. Some deposits (Red Dog, Alaska and HYC, Australia) are characterized by very fine-grained intergrowths of silica and sphalerite (individual sphalerite grains are 0.5 to 50 microns) or sphalerite with other sulfide minerals ( <100 microns) (McClay, 1983; Moore and others, 1986).Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.Rutile is a commercially important titanium mineral, although most titanium dioxide is produced from ilmenite. Rutile has minor uses in porcelain and glass manufacture as a colouring agent and in making some steels and copper alloys. Rutile is also used as a gem, but artificial rutile produced by the flame-fusion (Verneuil) process is superior ...

Chalcopyrite is one of the most important copper ores and is widely distributed in various geological environments. It is often found in association with other sulfide minerals.Sulfides occur in all rock types. Except for dissemination in certain sedimentary rocks, these minerals tend to occur in isolated concentrations which make up mineral bodies such as veins and fracture fillings or which comprise replacements of preexisting rocks in the shape of blankets. Sulfide mineral deposits originate in two principal processes, both of which …
Minerals of the Zn-Cd-S-Se system that formed by moderately reduced ~800–850 °C combustion metamorphic (CM) alteration of marly sediments were found in marbles from central Jordan.
