Good news: Green Chemistry in Modern Mining and Rare Earth

Green chemistry has been defined as the design of chemical products and processes to reduce or eliminate the use and generation of hazardous substances [1]. This definition was formulated in the early 1990s and has since gained acceptance throughout the world, especially in the chemical and pharmaceutical industries [1,2].

Note that this definition does not say which “things.” The implication is that AI could eventually end up doing all “things” that humans do, and do them much better—that is, achieve super‐human performance as witnessed recently with AlphaGO 13 and AlphaGO Zero. 14 This implication is sometimes called the central dogma of AI.

Froth Flotation Process - Detailed Explanation With

Froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out.
