Leaching of Rare Earth Elements from Various Sources

<p>The proposed book is a compilation of a Special Issue on Leaching of Rare Earth Elements from Various Sources published in the journal <em>Minerals</em> in 2020. There are 10 papers contributed by experts in the area and these can be grouped into four categories: leaching from low-grade ores including coal clay soil and red mud; pre-treatment and leaching; recycling; and precipitation and nano-hydrometallurgy. </p><p>Although these articles are available in the journal <em>Minerals</em> it is convenient to compile the most valuable information into a book form so that scholars and industrial practitioners can have easy access to it when they need it where the Internet is not easily available. I strongly believe that the book on a very specialized topic matter such as modern extraction technologies of rare earth elements will contribute greatly to the fast-growing industry that needs rare earth elements.</p>
