Bornite Meaning: Crystal Healing, Mineralogy, and History

Bornite is a type of sulfide, minerals in which sulfur has been combined with one or more metals. They tend to have simple structures and often have a metallic luster. In the case of Bornite, the sulfide combines with copper and iron. When tarnished, it may have a colorful iridescence and be called Peacock Ore.

The key differentiating factor between the two minerals is the presence of iron in bornite (Cu5FeS4) and the lack thereof in chalcocite (Cu2S). This study considers bornite and chalcocite microflotation, adsorption studies and zeta potential measurements, and three key factors were explored: pH, galvanic interactions and collector adsorption.
