The Lumwana copper mine is a conventional open pit (truck and shovel) operation. It's located about 100 kilometers west of Solwezi in Zambia's Copperbelt — one of the most prospective copper regions in the world. Lumwana ore, which is predominantly sulfide, is treated through a conventional sulfide flotation plant, producing copper ...
Life
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria.

Chalcocite
Chalcocite (/ ˈ k æ l k ə ˌ s aɪ t /), copper(I) sulfide (Cu 2 S), is an important copper ore mineral.It is opaque and dark gray to black, with a metallic luster.It has a hardness of 2.5–3 on the Mohs scale.It is a sulfide with a monoclinic crystal system.. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning "copper".
Bornite: A mineral, an ore of copper, often called "peacock ore"
Bornite is a copper iron sulfide mineral with a chemical composition of Cu 5 FeS 4. It occurs in igneous, metamorphic, and sedimentary rocks. Minable concentrations of bornite occur in hydrothermal veins, contact metamorphic zones, and in the enriched zone of many sulfide mineral deposits.
