Copper Mining and Production Processes Explained

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 (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Mineral processing | metallurgy | Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations ...

Innovations in Copper Mineral Processing Technology

• Heavy medium separation is the process of separating copper ores by a specific medium (ferro-silicon) density. • Testwork on copper ores at a size range of -76 mm+ 6 mm and a medium density of 2.8 demonstrated that 49% of the mass can be rejected whilst only losing 14% of copper – …

Copper extraction - Wikipedia

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

An Overview of Copper Smelting in Southern Africa

Israel. Copper is the world's oldest metal and was used more than 5000 years ago for water plumbing in the Pyramid of Cheops in Egypt. The Egyptians obtained their copper from Israel and from Cyprus. Throughout the second millennium BC, copper was produced in Cyprus by extracting it from copper sulfide ores.

COPPER Copper production - Repository

About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Plant Flowsheet. The standard process for this plant is shown on the preliminary flowsheet on Figure 5. The list of equipment is shown on Table 3. Ore will be brought by the miners to the plant in small trucks with an average size of 10 tonne lots and the material will be dumped on a …

Copper recovery using leach/solvent extraction ...

extraction/electrowinning plant Ranchers leached run of mine copper oxide ore (> 0.5% Cu) placed in a sealed canyon in 20-foot layers (heaps) by distributing dilute sulphuric acid over the fresh ore via spray emitted from needle valves with pipes and needle valves placed to ensure complete coverage of the ore. New heaps were built over old heaps.

12.3 Primary Copper Smelting

atmosphere. Crushing and grinding systems used in ore, flux, and slag processing also contribute to fugitive dust problems. Control of SO2 from smelters is commonly performed in a sulfuric acid plant. Use of a sulfuric acid plant to treat copper smelter effluent gas streams requires that particulate-free gas


Oxide ore with a low copper content will be treated at a nominal throughput of 500000, t/year through a hybrid carbon-in-leach (CIL) plant to recover gold as bullion. Sulphide ores will be treated at a nominal throughput of 250,000 t/year through a conventional froth flotation plant to produce a copper-gold concentrate. A block


The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Copper Mining and Processing: Everything you Need to Know

The Basics of Copper Mining and Processing. 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.

1.3 Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter 3.3. Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a pre-enrichment process for refractory ores.
