Copper Mining and Extraction: Oxide Ores
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining The smelting stage gives the name pyroprocessing OUR MINING PROCESS Learn how FreeportMcMoRan Inc carefully drills deep into the earth mining for copper ore Follow the process each step of the way from Drilling to Electrowinning to Market Take an inside look at how the raw ore is sifted, refining and manufactured into the copper products you depend on Drilling Blasting Loading Hauling Crushing Conveying Concentrating Smelting OUR MINING PROCESSThe 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 larger Copper Ore Processing Methods
copper ore mining process enjob2013
In copper ore mining process, the raw material is first quarried from the copper mountain and the raw materials are got Next is to process and mine the raw copper materials They are sent into jaw crusher for primary crushing through vibrating feeder After the raw materials are crushed into coarse ones, with belt conveyor, they enter into impact crusher or cone crusher for the secondary 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) Having a quick look now at how porphyry ores are treated and the metals extracted There are two main Copper Mining Extraction Process Flow ChartCopper ore is extracted using two basic methods of mining open pit or underground mining 3 Processing 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 From Ore to Finished Product Copper

We 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 treatmentSince the introduction of hydrometallurgical process for copper in the late 1980s, it has been widely used in China, especially for copperbearing materials that cannot be effectively recovered by conventional processing methods, such as waste rock from openpit ore stripping and lowgrade copper oxide ore Hydrometallurgical process is the process of extracting copper from pregnant liquid by Copper ore processing technology development and research Production geologists use information they obtain from sampling, testing, mapping and observation to determine the most efficient and effective mining techniques, as well as to identify the grade (amount of mineral) in the ore In gold and silver mining, grade is reported as grams per ton Copper grade is reported as a percentage It is important to know the grade to determine which rock is The Mining Process Newmont Corporation About Us
