process of copper production from copper ore stage


Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing 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.

The Extraction of Copper

Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.

The development stage usually takes 4-12 years to open an ore deposit for production, and may cost anywhere from $1 million to over $1 billion to complete depending on the type of mine. Development involves extensive pre-development planning and paperwork. Budget and financial reports are prepared and permits are requested.

Copper

Production in the Old Copper Complex in Michigan and Wisconsin is dated between 6000 and 3000 BC. Natural bronze, a type of copper made from ores rich in silicon, arsenic, and (rarely) tin, came into general use in the Balkans around 5500 BC. Bronze Age

The Extraction of Copper

The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).

copper extraction and purification

The process. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage).

How copper is made

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

Copper

(ii) The leaching process. Copper is obtained from its ore by treating the ore with a solution of copper(ll) chloride and iron(lll) chloride: Copper is recovered in the form of copper(l) chloride. To keep the compound in solution, sodium chloride is added.

Copper Ore Processing Methods

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,

Copper Mining and Extraction: Sulfide Ores

After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate. It is valuable enough to ship to other plants and other countries for processing. For example China, Germany and Japan are major copper producers that use concentrate from around the world.

Mineral processing. These produce air bubbles in the ore-water mixture, or slurry. The reagents provide an attraction between the surface of the copper minerals and the air bubbles. As the bubbles rise to the surface, they carry the copper minerals with them, leaving gangue minerals in the cell to be discarded as tailings.

TRIBAL MINING COPPER MINING EDUCATIONAL AND PROCESSING

conductivity. Copper ore deposits are found on every continent, and it has been mined around the world for more than 10,000 years. It is a necessary component for manyn the modern world. The steps involved in opening a mine and processing copper ore into a final product are very complex.

COPPER Copper production

Copper production 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

Copper Production: How Is Copper Made?

Manufacturing Process of Copper. Regardless of the ore type, mined copper ore must first be concentrated to remove gangue, or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill.

Copper Production in Zambia in Five Easy Steps. How it is Done

Oxide ore treatment process: Copper is liberated from oxide ore through a chemical process known as leaching and solution extraction. The final step is electrowinning, which uses an electrical current to produce sheets of copper that are 99.99% pure and ready for shipping to world markets. Step 5. The copper is used in many applications. Copper is strong, and has excellent thermal and electrical properties. It is used mainly in electrical wiring (60%), roofing and plumbing (20%) and

Copper Mining & Extraction Process Flow Chart. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. This process as the advantage of avoiding the smelting and refining stages required for sulfide ores.

Copper mining. From ore to copper.

The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass.

Copper mining. The main stages.

Copper mines are only set up where there is more than 5kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The flow chart shows you how copper is extracted from its ore and converted into pure metal. Roll over each stage to get a summary and click to find out more.
