1 Froth Flotation – Fundamental Principles
This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.
Bornite: A mineral, an ore of copper, often called "peacock ore"
"Peacock Ore" Bornite is easily recognized because it tarnishes to iridescent shades of blue, purple, red, green and yellow. It is commonly called "peacock ore" or "purple copper ore" after these iridescent colors. Upon surface exposure, bornite will weather to chalcocite or other copper minerals.
