process of copper mines
From its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stag When it is recycled it ,
Oxide ore – treatment process: Copper is liberated from oxide ore through a chemical process known as leaching and solution extraction The final step is electrowinning, which uses an electrical current to produce sheets of copper that are 9999% pure and ready for shipping to world markets Step 5 The copper is used in many applications
Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine) These produce many millions of tonnes of copper ore per year
Copper Mining Info The above flowsheet shows a basic copper mine process, from mine to metal There are two distinct types of copper ore, the sulfide ore and the oxide ore The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached First the copper ore from a open pit mine is blasted, loaded and .

Copper Mining Videos Copper is a chemical part that carries the chemical symbol Cu and with an atomic number 29 It is a soft metal with glowing electrical conductivity and is somewhat flexible in its pure state and has a reddish pink gleam which is strange for metals which are usually shiny white
Copper Mining Process Flow Chart In copper mining process flow sheet, the copper ore deposit will be first extracted by open pit quarrying or underground mining methods The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus ,
Process The 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
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 open-pit 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
The copper is recovered by electrolytic refining Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 01% copper - for this reason, leaching extraction is growing in importance
Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting Smelting these materials would require too much energy and very large furnace capaciti The copper ore coming from the mine (05 – 1 %
