    By mining properties of the constituent atoms, three materials research relevant tasks, namely, separation of a number of compounds into subsets in terms of their crystal structure, grouping of an unknown compound into the most characteristically similar peers (in one instance, 100% accuracy is achieved), and specific property prediction (the melting point), are explored.

    Magnetic Separation Magnetic separation is aprocess in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. Magnetism is ideal for separating mixtures of two solids with one part having magnetic properties.

    Neodymium and dysprosium are two rare earth elements (REEs), out of a group of 17 elements. Due to their unique properties, REEs gained increasing importance in many new technologies, like wind turbines, batteries, etc. However, the production of REEs requires high material and energy consumption and is associated with considerable environmental burdens.

    Before the minerals can be used, they need to be separated from the waste rock. A number of different separation techniques are used. These techniques are based on the properties of the minerals. Different minerals are often found together, for example copper and zinc, gold and silver or the PGMs.

    Mining: The process of extracting the ores from the Earth's crust is calledmining. Gangue or Matrix: The rocky impurity associated with an ore is called gangue or matrix. Flux: It is the substance added to the ore to reduce the fusion temperature and to remove the impurities. E.g. Calcium oxide (basic), Silica (acidic).
