is the traditional method of extracting copper

Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. Traditional methods Copper is usually sourced from copper-rich ores in two main methods Copper can be smelted in a furnace by heating it with air to produce crude 3.3.4 Copper extraction :: GCSE notes Pages

3.3.4 Copper extraction :: GCSE notes Pages

Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore can Large areas of land, Copper would be too expensive to extract from this contaminated land using the traditional method of quarrying and then heating in a furnace.

This is happening in particular with nickel and copper as their ores are becoming more and more scarce; Phytoextraction and bioleaching (bacterial) are two relatively new methods of extracting metals that rely on biological processes; Both of these methods avoid the significant environmental damage caused by the more traditional methods of miningCopper is a wildly used resource that can be found throughout modern society. Copper has traditionally been extracted from high grade ores using large scale mining projects.Due to pressures on copper reserves, industries are driven to extract copper from lower grade ores.This has spurred the development of new ways of extracting copper, including Biological Methods of Extracting Metals Revision MME

Copper Production: How Is Copper Made? ThoughtCo

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit 90% of ore is mined using the open pit method. Why is extracting copper the traditional way bad for the environment?What is the traditional method of extracting copper?

GCSE CHEMISTRY Extraction of Copper Thermal

Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide.This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature ofcopper extraction and purification chemguide

Why are biological methods being used to extract copper?

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.Due to lower recovery and high cost of traditional mining methods, the ZCM has been extracting copper using bioheap leaching since the 1998. A Solvent Extraction/Electro-Winning (SX-EW) commercial bioleaching plant, designed by China ENFI Engineering Corporation was constructed in 2000 and has been operational since the 2005 with a Copper Bioleaching in China: Review and Prospect
