What are three negative impacts of phosphate mining?
Most of the impacts are being reflected in the form of changes to local hydrology, water contamination, water consumption, air pollution and human risk.
What are the environmental impacts of mining?
Mining: Environmental Impacts Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes. Modern mines as well as abandoned mines are responsible for significant environmental damage throughout the West.
What are the 5 environmental impacts of mining?
These activities make a direct impact on our air, water, public health, wildlife and habitat, water use, land and soil use and global warming.
Is phosphate mining sustainable?
It is well known that phosphate is a non-renewable resource essential for plant growth and crop production, and it is, therefore, vital to feeding the fast growing population of the world.
Is phosphate dust harmful?
Inhalation exposure has resulted in respiratory tract irritation and coughing in humans. Chronic (long-term) exposure to white phosphorus in humans results in necrosis of the jaw, termed “phossy jaw.” EPA has classified white phosphorus as a Group D, not classifiable as to human carcinogenicity.
Why do we need phosphate mining?
But we can provide more by mining phosphate rock and turning it into fertilizer to spread on the land. It takes one ton of phosphate to produce every 130 tons of grain, which is why the world mines about 170 million tons of phosphate rock every year to ship around the world and keep soils fertile.
What are the environmental and social impacts of mining?
Environmental and social impacts are divided into waste management issues, impacts to biodiversity and habitat, indirect impacts, and poverty alleviation and wealth distribution. Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment.
What are the positive and negative effects of mining?
Mining can impact local communities both positively and negatively. While positive impacts such as employment and community development projects are important, they do not off-set the potential negatives. We have found mining can negatively affect people by: exposing them to harassment by mine or government security.
What are the three environmental impacts of mining?
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust and …
Why do we need phosphate?
Phosphate is necessary for the formation of bone and teeth. Phosphate is also used as a building block for several important substances, including those used by the cell for energy, cell membranes, and DNA (deoxyribonucleic acid). The body obtains phosphate from foods and excretes it in urine and sometimes stool.
Why do we mine for phosphate?
Worldwide, more than 85 percent of the phosphate rock mined is used to manufacture phosphate fertilizers. The remaining 15 percent is used to make elemental phosphorus and animal feed supplements, or is applied directly to soils. Elemental phosphorus is used to manufacture a wide range of chemical compounds.
Why is phosphate bad for you?
Eating too many foods containing sodium phosphate additives can raise phosphate levels in the body to an unhealthy level. Studies have linked high levels of phosphate with conditions like heart disease, decreased bone density, premature aging, kidney issues and even early death ( 7 ).
What are the environmental impacts of phosphate mining?

Are there any toxic phosphate mines in Florida?
Florida is home to at least twenty seven radioactive phosphogypsum stacks and each toxic stack is still growing. The “stacks” are so toxic, the DEP will not allow the phosphate industry to move the phosphogypsum off site or sell it.
Who are the largest phosphate mining companies in the world?
As cheap phosphorus becomes more scarce, it’s value rises, and these industries stand to make more money than ever before until the resource is all but exhausted. Currently, Mosaic is the largest phosphate mining company in the world, and is in the process of expanding some of their current mining sites in Florida.
