  • 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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the largerProcessing of Copper Ore The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces This is accomplished by a variety of subsequent processing steps 4 Beneficiation of Copper Ore The next step in processing is called beneficiation This is the first step in concentrating the copper into a more useable form 5 Smelting and ExtractionFrom Ore to Finished Product Copper26/09/2019· Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries Copper is typically extracted from oxide and sulfide ores that contain between 05 and 20% copperCopper Production: How Is Copper Made?

  • Copper Mining and Extraction Sulfide Ores

    The world’s largest copper ore deposits are found in Chile on the west coast of South America This is due to the volcanic activity that is part of the process that created the Andes mountain chain This is the west coast of South America, showing the line of volcanoes that stretches along the whole west coast of the continent They are caused by subduction of the Nazca tectonic plate underThe main copper ores are: chalcopyrite bornite malachite Grinding: The ore is crushed then ground into powder Concentrating: The ore is enriched using a process called froth flotation Unwanted material (called gangue) sinks to the bottom and is removed Roasting: This is where the chemical reactions start The powdered, enriched ore is heated in air between 500 °C and 700 °C to removeCopper mining The main stagesCertain bacteria can break down lowgrade ores to produce an acidic solution containing copper ions The solution is called a leachate and the process is called bioleaching Bioleaching doesBiological methods of metal extraction Higher Material

  • copper extraction and purification chemguide

    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 Concentration of the copper(II) sulphate solution by solvent extraction The very diluteThe 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 Some of these steps are conducted at the mine site itself, while others may be conducted at separateHow copper is made material, used, processing, stepsWe shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process Mining for Copper Bearing Ore There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment The major producers of copper ore are ChileCopper Smelting Process Furnaces Used, ByProducts,

  • Copper mining The main stages

    The main copper ores are: chalcopyrite bornite malachite Grinding: The ore is crushed then ground into powder Concentrating: The ore is enriched using a process called froth flotation Unwanted material (called gangue) sinks to the bottom and is removed Roasting: This is where the chemical reactions start The powdered, enriched ore is heated in air between 500 °C and 700 °C to removeExtracting iron and copper Ores Unreactive metals such as gold are found in the Earth's crust as the uncombined elements However, most metals are found combined with other elements to formExtracting iron and copper Obtaining and using metalsCertain bacteria can break down lowgrade ores to produce an acidic solution containing copper ions The solution is called a leachate and the process is called bioleaching Bioleaching doesBiological methods of metal extraction Higher Material
