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 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 copper ore usually contains a large amount of dirt clay and a variety of noncopper bearing minerals The first step is to remove some of this waste material This process is called concentrating and is usually done by the flotation method 3 The ore is crushed in a series of cone crushers

The Life Cycle of a Mine The stages in the life cycle of a mine are 1 Prospecting and Exploration 2 Development 3 Extraction and 4 ClosureReclamation Each of the stages may overlap with the next and is very lengthy and expensive

A look at the underground mining process The Resolution Copper deposit lies more than a mile beneath the surface The most viable way to recover this ore body is by going underground using a process called block caving Block caving is a proven mining method using advanced technologies

Mining of copper ores is carried out using one of two methods Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels called adits to reach the ore

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 05 by mass Ideally the figure should be closer to 2 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

In recent years there has been renewed interest in coppernickel mining in Northern Minnesota particularly by the PolyMet Mining Corporation PolyMet and Twin Metals Minnesota Twin Metals These companies are pursuing mining in the same general locations AMAX and

Mar 04 2020 · For coppercobalt ores a sulfide concentrate is roasted under controlled conditions to transform most of the cobalt sulfide to a soluble sulfate while minimizing the change of copper and iron to their watersoluble states The product is leached the resulting solution is treated to remove copper and iron and the cobalt is finally recovered by electrolysis

Current technology in mine dump preparation being practiced successfully by various operations in the leaching of copper is as follows Removal of all vegetation in area to be overdumped Compaction of area and emplacement and compaction of two feet of clay material for a base When economically

This crucial process which is generally conducted at or very near mine locations to save on transportation costs involves grinding mined ore to roughly

Each year the mine has the capacity to process about 260000 tons of copper concentrates which yields 132700000 pounds of copper and 1234000 ounces of silver Annually the Mission mine pays royalties and taxes to the State of Arizona and royalties to the Tohono O’odham Indian

The copper mining process begins with drilling and blasting Large drilling rigs bore a carefully designed pattern of holes approximately 12 inches in diameter and 60 feet deep into the rock

Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining 1232 Process Description24 Mining produces ores with less than 1 percent copper Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper

Copper ore is mined in our X41 and Enterprise underground mines where it is roughly crushed then hoisted to the surface for processing From here it is fed through a series of ball mills that grind the rock into a fine dust This dust is then mixed with water and reagents in our concentrators flotation circuit

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

Copper mining has been a major industry in the United States since the rise of the northern Michigan copper district in the 1840s In 2009 domestic mine production in the United States was valued at approximately 62 billion The principal mining States in order
