The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
Copper ore has a moderate hardness, typically ranging from 3 to 4 on the Mohs scale. The specific gravity of copper ore ranges from 2.5 to 3.5, depending on the type and mineral content. Copper ore is a good conductor of heat and electricity. Copper ore is not highly reactive, but can react with strong acids and oxidizing agents.
Porphyry copper deposits are large. They commonly consist of hundreds of millions to billions of tonnes of ore. However, they contain typically only 0.5–1.5% copper and are therefore classified ...
Bornite, commonly referred to as "peacock ore," is a captivating mineral known for its striking and iridescent appearance. This mineral, composed primarily of copper iron sulfide (Cu5FeS4), draws its nickname from the kaleidoscope of colors that adorn its surface, resembling the vibrant plumage of a peacock. Bornite's hues range …
The area influenced by any given hole is found as follows: (1) Divide angle at hole by 180°. (2) Multiply total area of entire prism by above result. (3) Multiply area found by (2) by the average thickness (found by solution of the formula) of ore in the hole, which thus transforms this smaller prism into volume.

The Mineral bornite. Bornite is an ore mineral of copper, and is known for its iridescent tarnish . "Peacock Ore", which is sold to amateur mineral collectors and tourists, is often labeled as a variety of Bornite. However, most Peacock Ore in reality is Chalcopyrite treated with acid, which produces a strongly-colored iridescent tarnish.

V = m ρ = 78.246g 19.32g/cm3 = 4.050 cm3 (5) (5) V = m ρ = 78.246 g 19.32 g / c m 3 = 4.050 cm 3. This is the volume of water displaced. Now we need the mass of water displaced, which is the bouyancy, or the difference in mineral mass in air and water. If we multiply both sides of Eq. 1.1 by V, we obtain.
