Rare earth metals have become an essential
resource in the present world due to technological development. Almost all the
countries try to develop their own technological goods, which has created a
huge demand for rare earth metals in the present world. However, the entire
process which is associated with extracting rare earth metals is very
disruptive to the world we live. They are being mined with a technology called
open pit mining techniques. When following this technique, heavy machinery and
equipment are used to create a hole in the earth and dig for rare earth metals.
During the refining process of rare earth
metals, a lot of byproducts are released to the environment. We can consider
them as pollutants since they have the potential to ruin the atmosphere. Moreover,
the process of extracting rare earth metals is a complex one and it is
associated with the usage of different solvents, acids and many other chemical
based materials. Last but not least, a large amount of energy and water is
consumed during the entire process. At the end of the day, it can produce
enormous amounts of waste gas, waste water and other forms of waste residue.
In February 2014, the Ministry of Industry
and Information Technology of China introduced a new plan which can reduce the
harm done by rare earth metals to the world. This plan is known as Cleaner
Production Technology Promotion Plan for the Rare Earth Industry. As mentioned
in this plan, the main objective of China is to enhance the speed of promotion
and industrial application of the process of separating low sodium and low
carbon free ammonia nitrogen rare earth oxide. They are also planning to
increase the efficiency of purification technologies, which create a lot of
damage to the earth. With this plan, China will be able to reduce the acid base
requirement which is associated with rare earth melting, and separation. If
they can continue this plan without any disruption, they will be able to make
the comprehensive use of available rare earth resources by the year 2017.
The government of China has asked relevant
departments to speed up the implementation process of this plan as soon as
possible. The sooner they implement it; the sooner they can reduce the damage
caused to the environment. The industrial technological level of China has
experienced a significant growth within the past few decades. However, this has
created a huge impact on the environment. The new plan will be able to save
373,000 tons of sodium hydroxide, 120,000 tons of hydrochloric acid and 50,000
tons of ammonia per year. By 2017, China will be able to experience the
benefits of the Cleaner Production Technological Promotion Plan of the Rare
earth industry.
