Primary Copper Smelting General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the megagrams (Mg)
Utah Copper had constructed the Magna Mill in 1906 as a plant for the coarse crushing, fine crushing, concentrating, and dewatering of copper ores. The site was selected because it was near water and high enough to make it easy to dispose of tailings (waste left over from milling).

Ore arrives from the mine at the Copperton Concentrator in about 28 minutes, where it is temporarily stored in a 500,000ton coarse ore stockpile. Concentrating In the second step of the production process, we concentrate the ore, which separates valuable minerals from the ore into a .
Material is drawn from the coarse ore stockpile using apron feeders and a conveyor belt to feed a 34 foot diameter, 13,000 Hp SemiAutogeneous Grinding (SAG) mill. SAG mill discharge is screened with the oversize returning via conveyor belt to the feed of the mill.
Stamp mills are used by miners to crush valuable ore and extract the metals within them. Gold, silver, and copper are common metals that are found within ore, and stamp mills allow these metals to be released from rock for further processing and refining.
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
Coarse rejects from the SAG mill are crushed in a 600 kW pebble crusher. In December 2017, a SAG Recycle Bypass System was installed to allow the coarse rejects to be diverted outside and later trucked to the stockpile. This has allowed maintenance on the conveyor belts downstream of the SAG mill without shutting down the grinding circuit.

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
There are little to no chemical data on waste rock. Data are presented for mill tailings and coarse coal refuse. Mill Tailings. Table 93 provides chemical composition data for selected samples of copper, gold, iron, leadzinc, molybdenum, and taconite tailings. As seen from these data, most tailings are .
