copper extraction and purifiion

Extracting copper from other ores. Copper can be extracted from nonsulphide 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 sulphuric acid to produce a very dilute copper(II) sulphate solution.

Copper Appliions in Metallurgy of Copper Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

Primary Copper Smelting

Process Description24 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purifiion, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, .

Smelting

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

 · For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper. If the copper ore contains 40 tons of calcite gangue, we can also say 40% of calcite in the ore. A gold deposit with a grade equal to 5 g/t (gram per ton) means that in one ton of the ore.

Copper Mining and Processing: Processing Copper Ores. A. Processing of Oxide Ore Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.

Processing Sulfide Ores Historically, miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls. However, with the implementation of the Mercury Export Ban of 2008 and the high costs of installing equipment to prepare sulfide ores for cyanide leaching, many companies are searching for alternative forms of processing their ...
