How copper is made
Concentrating. The copper ore usually contains a large amount of dirt, clay, and a variety of noncopper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.

Copper Ore
Concentration by Froth Flotation ( Chapters 3 and 4Chapter 3Chapter 4) The copper ores being mined in 2010 are too lean in copper (–2% Cu) to be smelted directly. Heating and melting their huge quantity of waste rock would require prohibitive amounts of hydrocarbon fuel.

Copper Mining Process | Information | New Mexico | Basics
Some ore types can be treated by crushing, grinding and mixing ore with water to produce slurry. The coppercontaining particles are then removed by a process called flotation. The product of this process is dry, gray powder called copper concentrate, which contains about 30 percent copper. The concentrated copper is sent by rail to a smelter ...

Copper Mining and Extraction: Oxide Ores
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining

Copper pyrites are concentrated by froth flotation process. In this process slurry of finely divided ore is taken in a large tank. Pine oil or eucalyptus oil is used as the frothing agent. Ethyl xanthate is added which is used as a collector (it increases the binding force between ore particles and forth). A mixture of all these things is agitated by current of air and froth is formed.

What Is Copper Smelting? (with pictures)
Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
