Specific gravity, 5.06–5.08. Refractive index, Opaque. Pleochroism, Weak but noticeable. Other characteristics, Magnetic after heating, iridescent. References. Bornite, also known as peacock ore, is a sulfide mineral with chemical composition Cu5FeS4 Its striking iridescence gives it the nickname peacock copper or peacock ore.
Copper is a chemical element with symbol Cu from Latin: cuprum and atomic number 29. Copper is essential to all living organisms as a trace dietary mineral because it is a contains between 1.4 and 2.1 mg of copper per kilogram of body weight. The original deadline to be in compliance was July 28, 2018, but on
The sulfide minerals in decreasing abundance include pyrrhotite, pentlandite, A, Skeletal copper light pink with small specs of cuprite bluish grey; North Mine . The hardness and specific gravity varies between 3.5–4.0, and 3.6–4.0,
Before you can calculate the potential mineral deposit value, you first need to gather some specific data, which I explain on Specific Gravity1, The density of the ore body i.e. the rock, 2.5 3. Convert Copper to Pounds and Gold to Ounces
