Fluorite occurs at the Sweet Home mine as a gangue mineral throughout the various vein structures. In different parts of the mine fluorite appears in many colors, from colorless to yellow, blue, green, purple and brown. Layers of colored fluorite crystals seldom reach 2.5 cm in thickness, and are sometimes interleaved with dickite and sericite.Fluorite occurs at the Sweet Home mine as a gangue mineral throughout the various vein structures.

Effect of Gangue Mineralogy on Flow Sheet Design and Plant ...

Copper-(Fe)-sulfide ore deposits typically have Cu grades varying from 0.5 to 5%. This equates to approximately 1.5 to 15% sulfide minerals, hence 85 to 98.5% of the remaining ore mass is comprised of gangue minerals. Many of the gangue minerals are relatively benign during mineral processing and subsequent hydrometallurgical and/or pyrometallurgical processing.Copper-(Fe)-sulfide ore deposits typically have Cu grades varying from 0.5 to 5%.
