Why are rare earth elements difficult to mine?

Rare earths are difficult to mine because they aren’t found in large quantities or veins like other minerals such as gold. They need to be separated from one another using a variety of mining and processing techniques.

Why are the rare earth metals so valuable and difficult to obtain?

Despite their high relative abundance, rare-earth minerals are more difficult to mine and extract than equivalent sources of transition metals (due in part to their similar chemical properties), making the rare-earth elements relatively expensive.

What are the problems with rare earth mining?

Mining for rare earth minerals generates large volumes of toxic and radioactive material, due to the co-extraction of thorium and uranium — radioactive metals which can cause problems for the environment and human health.

How is mining for rare minerals affecting our environment?

This means of extraction results in the destruction and contamination of the natural water system. Unique plants and animals lose access to groundwater and watering holes. There have also been reports of freshwater becoming salinated due to extensive acidic waste water during lithium mining.

How are rare earth metals extracted?

Currently, the raw materials for producing rare earth elements are their chloride and fluoride. Industrial mass production on mixtures of rare earth metals generally employs the molten salt electrolysis method. Meanwhile, the electrolysis process includes two methods: chloride electrolysis and oxide electrolysis.

What is rare earth and why is it important?

“Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions.

How does rare earth affect the environment?

A half century of rare earths mining and processing has “severely damaged surface vegetation, caused soil erosion, pollution, and acidification, and reduced or even eliminated food crop output,” the council reported, adding that Chinese rare earths plants typically produce wastewater with a “high concentration” of …

Why is mining harmful to the environment?

Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local …

Why do we need rare earth minerals?

Rare earth elements (REEs) are crucial for production of clean energy, electric vehicles, consumer electronics, national defense and more. China controls more than 80\% of global production and supply, putting supply chains and national security at risk.
