safety regulations for dishes in a hotel or restaurant 2017 How does Mining Affect the Environment
Mining refers to the process of extracting metals and minerals from the Earth.
Gold, silver, diamonds, iron, coal and uranium are only a few of the large quantities of metals and minerals obtained through this process.
Large areas of land need to be cleared for mining activities.
Chemicals used during mining often leak into the environment, resulting in a large numberPollution of scale.
In fact, mining is a source of substances that are not available to all industrial processes or agriculture.
Mining makes huge profits for companies that own them and offer jobs to a large number of people.
This is also a huge source of income for the government.
Although mining is economically important, its impact on the environment is an urgent issue.
Mining needs to clean up large areas of the forest so miners can dig in the land.
For this reason, big-
Large-scale deforestation is required in areas where mining must be done.
In addition to clearing the mining area, there is also a need to reduce vegetation in the adjacent areas in order to build roads and residential facilities for mine workers.
The human population has brought about other activities that endanger the environment.
For example, the various activities of the coal mine release dust and gas into the air.
Mining is therefore one of the main causes of deforestation and pollution.
Previously buried metal sulfide was exposed during mining activities.
When they are in contact with oxygen in the atmosphere, they are converted into sulfuric acid and metal oxides.
These compounds are mixed in local waterways and contaminated local rivers with heavy metals.
Chemicals such as mercury, cyanide, sulfuric acid, arsenic and mercury are used at all stages of mining.
Most chemicals are released into nearby water bodies and are responsible for water pollution.
Although tailings (pipes) used to dispose of these chemicals into water bodies always have the possibility of leakage.
When these chemicals slowly penetrate into the layers of the Earth, they reach the ground water and pollute the ground water.
Releasing toxic chemicals into the water is clearly harmful to the flora and fauna of the water body.
In addition to pollution, the mining process requires water from nearby water sources.
For example, water is used to wash impurities in coal.
As a result, the water content of a river or lake that is using water is reduced.
The creatures in these bodies of water do not have enough water to survive.
River dredging is a way of gold mining.
In this method, gravel and mud are sucked out from specific areas of the river.
The remaining mud and gravel were released back into the river after the gold debris was filtered out, although the location was different from where they were taken away.
This destroys the natural flow of the river and can lead to the death of fish and other creatures.
Despite the measures taken to discharge chemical waste into nearby rivers through pipelines, a large amount of chemicals still leak onto the land.
This changed the chemical composition of the land.
In addition to this, since these chemicals are toxic, they make the soil unsuitable for plant growth.
In addition, organisms living in the soil find that polluting the environment is not conducive to their survival.
Sometimes, liquid waste generated after metal or mineral extraction is treated in mining pits.
When the pits are filled with tailings, they become a pool of accumulation.
This becomes a breeding ground for water.
Diseases that cause biological reproduction such as insects and mosquitoes.
Forests cleared for mining purposes are home to a large number of creatures.
Cutting forests without distinction causes a large number of animals to lose their habitat.
This puts the survival of a large number of animal species at stake.
Cutting trees themselves poses a huge threat to many plants, trees, birds and animals living in the forest.
The rainforest is the largest source of oxygen, wood and medicine on Earth.
Amazon rainforest is known for its gold sands.
After the Flood (flood zone), gold was found on both the river and the river banks.
Hydraulic mining technology is used for gold mining.
The method includes blasting on the river bank.
This has caused irreversible damage to trees, birds and animals.
Separation of sediment and mercury from gold
Gravel deposits, small-
Miners of smaller sizes than industrial miners may overlook the release of some mercury into the river.
This Mercury enters the food chain through aquatic animals and their predators.
Highly toxic compound "cyanide" is also used to separate gold from deposits and rocks.
Despite all the precautions taken, it sometimes enters the surrounding environment.
People who eat fish have a greater risk of taking this toxin.
In Guyana, in 1995, more than 4 billion litres of cyanide-containing wastewater slid into the tributary of Essequibo;
When the tailings pond filled with cyanide waste collapsed.
All the fish in the river are dead, the lives of plants and animals are completely destroyed, the soil of the floodplain is severely poisoned, and the land is useless to agriculture.
The main source of drinking water for local residents has also been contaminated.
This is an important scene.
Back ecology
Tourism on the river.
When trees are cut down (forest cleaning for road and mine construction, timber for immigrant population, workers, etc ).
) Pollution of water sources, migration or death of animal populations.
In addition, hunters are hired to provide food for people who work in the mining area. The Kahuzi-
Congo's Bianca National Park was declared a "world heritage site" in 1980 for its abundant biological resources"diversity.
The purpose behind this is to protect several types of animals and plants.
With thousands of people starting to extract ta and tin stones from hundreds of locations throughout the park, most large animals are at 15-20 years.
Grauer's number of gorillas found in this area alone has decreased significantly.
Statistics show that there are only 2-
There are 3,000 gorillas left in guoler.
The Indonesian government has sued a gold mining company for throwing toxic waste such as arsenic and mercury into Buyat Bay.
The fish in the Bay was killed.
People in the surrounding areas can no longer eat fish.
They already suffer from various diseases such as persistent headaches, rashes, tumors, and difficulty breathing.
The impact of mining on the environment may not be immediately apparent and will usually be noted in a few years.
While developed countries have strict norms in mining, such rules are easily overlooked in countries that lack strict monitoring of mining procedures.
In this case, the impact on the environment may be devastating.
Whether it's due to ignorance of the regulations or just an abnormal accident, something like the 1995 oil spill in Guyana could happen again.
This highlights the fact that issues such as the impact of mining on the environment deserve serious consideration.
