In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment.
There are different phases of a mining project, ... involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of large-scale mining projects involving these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods ...
The process of smelting is when industrial factories extract or smelter purer and more refined metals from ores. Metals like copper or lead are often extracted using this process from earth samples and deposits. Although smelting helps with metal productions, there are many disadvantages to smelting that impact the environment.
Copper is a good electrical conductor for wiring; it is not reactive so can be made into water pipes Lead can be bent easily so is used to seal joints on roofs Steel is strong for girders and scaffolding Aluminium alloys are corrosion resistant Steel is a commonly used metal and is often used in the
However metal–rich ores e.g. copper ores, are being depleted and because traditional mining and extraction methods have major environmental impacts, there are important issues involved and to be resolved in the future exploitation of metal ore reserves.
What Are the Advantages and Disadvantages of Copper? Copper is the metal of choice for conductive wiring and circuits, but has become more expensive over the years. Copper is used for a variety of artistic purposes. The high price of copper is only …

2018-04-05· Aug 10, 2012 The final frontier of mining is set to be explored in the very near future, Minerals of Canada has been granted a 20 year licence to extract copper and the possible advantages and disadvantages of mining under the sea.
Advantages: Raw metal can be a source of valuable revenue. It can be exported and sold to countries that consume metal the most, such as China and the United States. Extracting raw metal also creates jobs for a lot of people, so does processing, refining, and transporting metal.
Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas.
These spillovers may outweigh the benefits from mining if most jobs go to outsiders, environmental degradation or community disruptions are large, tax revenues accrue to national governments and are not returned sufficiently to local communities, or governments spend mining revenues unwisely. These social risks associated with mineral exploration and mining are not the subject of this paper ...
Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface.
2013-06-04· Additionally, man-made processes like mining, manufacturing and farming may also put copper into the environment. While copper compounds break down in the open environment, the pure copper particles do not break down and remain behind in our air, food and water.
secondary lead metallurgy equipment. It is good to use converter to dispose lead-acid battery plate for secondary lead.Converter has higher thermal efficiency,higher operation rate than reverberatory furnace,it also has some advantages as below:high degree of mechanization,good working conditions,good environment protection effect.
Studies of copper mine workers both pre and post mortem have detailed the risk of chronic copper exposure and broken the risk up by parts of the copper mining processes (e.g. smeltering, converting, plating) (11,12,13,14).
Overview. Unregulated mining has the potential to release harmful substances into the soil, air, and water. Mission 2016 proposes that governments enforce regulations on companies and use cutting-edge technology to reduce the damage from mining-related sources.

In a nutshell, although it is an undeniable fact that mining affects our world enormously, we ought not to demonize its practice while its benefits are constantly enjoyed by the large majority of people.
About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it …
The advantages and disadvantages of mining can be determined based on facts uncovered by scientists and by personal opinions. One definite advantage is the fact that it brings … in large amount of profits for the companies doing the mining.
The major drawback of industrial mining is the damage mining operations cause to the environment. Removal of large areas of topsoil can destroy habitats, and the chemicals used in mining operations can leach into the groundwater and pollute the area.
The use of copper and copper-containing materials will continue to expand and may lead to an increase in copper mining and production. However, the copper mining and manufacturing industry and the consumer do not necessarily enjoy a favorable relationship. Open pit mining, copper mine tailings, leaching products, and deposits of toxic metals in the environment often raises concerns and ...
Mountaintop-removal mining, for example, allows mining companies to extract a significant amount of coal at a far lower cost, but its destructiveness has led to protections for the environment. Traditional forms of mining can be unsafe for workers. Fires and collapses can be deadly, and the health effects of mining can be devastating.
Both have advantages and disadvantages. Both are potentially environmentally catastrophic but can be done safely with a lot of cost or at least the effects mitigated during mining, or after the mine is played out (e.g. no more ore to mine cheaply). This extra cost is the reason that mining is usually, but not always, environmentally catastrophic.
On-the-Job Risks of Mining Many people are aware that the mining profession can be very dangerous, if only due to news stories about mining catastrophes — you may remember the trapped Chilean miner incident from a few years ago.
Environmental Impacts. Both surface and underground mining can have severe environmental impacts by disrupting the landscape, removing vegetation and topsoil, contaminating the air with dust and toxic substances, and causing toxic compounds in mining spoils to percolate into the groundwater.
Environmental impact of mining - Wikipedia, the free encyclopedia. The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. ....
Some examples of how copper may be released into the environment are through copper mining, agriculture and manufacturing activities. Copper may also enter the environment through natural processes, such as volcanic eruptions, windblown dusts, decaying vegetation, and forest fires. Additionally, copper is found in most sewage due to the corrosion of copper plumbing.
