Solvent extraction involves stripping the copper from the pregnant liquor using an organic solvent, or extractant. During this reaction, copper ions are exchanged for hydrogen ions, allowing the acid solution to be recovered and re-used in the leaching process.
In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment.
The Mt. Gordon copper process and the Sepon copper process both use autoclave processes in the overall metallurgical circuit. In the Mt. Gordon circuit, the autoclave was used to leach copper while at Sepon the autoclave is used to produce acid and ferric sulfate to meet the requirements of an atmospheric leach.
Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides.The percentage of copper in the actual ore is too low for direct extraction of copper to be viable.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Technologies in Exploration, Mining, and Processing INTRODUCTION The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use.
The process from exploration site selection, through target generation, resource evaluation and ore deposit definition costs tens of millions of dollars, before the potential for a copper mine is confirmed, with that the path to production is still many years away.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago.

Each of the different natural forms of copper requires distinct mining and processing steps that eventually lead to 9.99% pure copper. C. Historical and Modern Copper Use The development of copper has a rich history.
extraction and processing of copper mining. We understand that every extraction and processing of copper mining job is different, and we strive to make sure every machine we construct is a custom solution that gets a specific job done right.
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.
Nov 03, 2012· 4 min video clip shows how copper is mined. It also shows the reduction process showing copper being reduced out of solution using electricity.
Mining and Processing Methods. Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites.
Most modern mining techniques have high water demands for extraction, processing, and waste disposal. Wastewater from these processes can pollute water sources nearby and deplete freshwater supplies in the region surrounding the mine.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and ...
