Copper Ore an overview ScienceDirect Topics

Copper is among the few metals known to ancient civilizations. Copper, gold, silver, platinum, and meteoric iron are the only metals found in their native state. However ∼90% of copper comes from sulfide ores. Most copper ores contain 0.5% Cu or less, iron being the principal metallic impurity. The ores are ground to a fine powder and concentrated (normally by floatation) to 20–25% Cu.

Chemistry of Copper Chemistry LibreTexts

Copper Cu PubChem

Copper is a metal that occurs naturally throughout the environment, in rocks, soil, water, and air. Copper is an essential element in plants and animals (including humans), which means it is necessary for us to live. Therefore, plants and animals must absorb some copper from eating, drinking, and breathing. Copper is used to make many different kinds of products like wire, plumbing pipes, and
