copper extraction and purification chemguide
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 of the ore Sulphide ores such as chalcopyrite areThe commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides The percentage of copper in the actual ore is too low for direct extraction of copper to be viable The concentration of ore is required and it is done by the Froth Flotation method Concentration of Ore: The ore is crushed into a fine powder and a suspension isExtraction Of Copper | Mining, Concentration, SmeltingEXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper Crashing and Grinding The ore is crushed then ground into powder CONCENTRATIONFloatation process The finely crushed ore is suspended in water containing a little amount of pine oil A blast of air is passed through the suspension The particles get wetted by the oil and float as a frothEXTRACTION OF COPPER

Extraction of Metals Extraction of Copper Copper is sometimes found as native metal Copper ores include copper(II) oxide and copper(II) sulfide Copper(II) oxide can be reduced by reaction with carbon 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 andreaction The impure copper is purified by electrolysis This table summarises the extraction methods used for different metals: Although an unreactive metal is found as the uncombined elementExtracting iron and copper Extracting and using metalsHow does the copper extraction process work? Most copper is refined from sulphide ores The process includes the following stages: The copper ores are mechanically crushed and ground The resulting mixture i s treated using flotation with air injection and agitation to leave concentrates containing around 30% copperCopper mining and the copper extraction process explained
Extraction Of Copper Process
A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of26/08/2015· Copper Mining & Extraction Process Flow Chart This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore)Copper Mining & Extraction Process Flow ChartExtraction of Metals Extraction of Copper Copper is sometimes found as native metal Copper ores include copper(II) oxide and copper(II) sulfide Copper(II) oxide can be reduced by reaction with carbon 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 andGCSE CHEMISTRY Extraction of Copper Thermal
