5.1 Process Overview 5.1.1 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations. In 2000, the principal mining States, in descending order, Arizona, Utah, New Mexico, and Montana, accounted for 99 percent of domestic production. Copper was also recovered at mines in three other States.

Crushed ore heap leaching (of secondary sulfides) consumes approximately half the energy of milling-flotation-smelting process
copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter.

The ground ore is mixed with water to form slurry which chemical reagents are added, and then aerated to produce bubbles. Using the principle that the hydrophobic ore particles attach to the bubbles, the target ores are recovered. From this process, copper concentrates with 20-40 %-Cu is produced, which is sent to a smelting and refining plant

Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding

The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation. The flow sheet depends on the mode of occurrence of the mineral

The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a collector chemical called potassium amyl xanthate (or the potassium salt of an alkyl dithiocarbonate).

The geological conditions create new challenges in your copper mine. Declining ore grades mean less metal production for each ton processed. And as you have to dig deeper and into harder rock you face longer haulage distances and increased wear of your equipment which translates into higher operational costs.

The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate. Today, more than 13% of all "new" copper is produced from leachates, which are normally concentrated using solvent extraction (SX) and stripped of their copper content by

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
