Copper Mining and Processing: Everything you Need to Know

Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes ...

How copper is made

Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of highgrade copper ore around Lake Superior began. The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States.

9 Ore Deposits and Economic Minerals – Mineralogy

Sometimes geological processes concentrate ore minerals in vein deposits consisting of veins that are centimeters to meters thick. If ore is distributed in many small veins, geologists call the deposit a lode deposit. Vein deposits account for most of the world's gold and silver mines, and also some copper and leadzinc mines.

Copper and gold have similar cyanide metallurgy depending on the nature of the minerals present. The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations.

Copper Smelting Process

 · We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper Bearing Ore. There are two egories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.

copper mines within the RTB Company ranked among the highestgrade copper mines (on average 5 – 6 % Cu in the ore). At the end of the century, the average Cu content in the RTB Bor mines fell to less than %, which is illustrated by Fig. 1. Consequently, it is now ranked among lowergrade copper mines in the world [9].

 · That's why I wanted to revisit the 2018 Mining Engineering magazine article, Improved flow measurement and control are key to efficiency, by Emerson's Alena Johnson. Alena opens describing the heap leaching process for copper: Copper ore is excavated from the ground, crushed and then spread in uniform layers on a pad.

Water Consumption at Copper Mines in Arizona

All mining needs water for mining and processing and copper mining is no exception. Arizona is mostly desert and, therefore, short of water. ... where the lixiviating solution percolates through the ore to release the copper ions into solution. If agglomeration is used the sulfuric acid starts to dissolve the copper from the minerals.
