Process and apparatus for producing elementary nanoparticulate mineral components and rare metal oxides therefrom using primary and secondary mineral resources by filling raw material (1,15,16,17) into a mixing tank (7), wherein it is diluted with water to a 20% by weight colloidal solution, then the colloidal solution is fed to a colloid mill (8) and dispersed into particles having an average particle size of up to 10 µm, then transferring it to a wet grinding attritor (9), the nanoparticulate colloidal solution thus obtained is passed under pressure to a classifying unit (10) in which its nanocrystallite content is separated into at least two size fractions, each size fraction being dried in a vacuum drier (11), while a further nanocrystallite fraction containing trace elements is separated by the vacuum drier (11), which is passed to a separator (13,11a) where adsorbed rare metal trace elements are separated.

The aim of the present invention is to provide a more cost-effective and space-saving alternative for sorting mixed inorganic waste from household collection into several fractions with less need for high-value industrial equipment than usual. The invention comprises an apparatus (100) for mechanically preselecting separately collected or presorted communal waste, the apparatus comprising: a ballistic separator (110) separating the feed waste into a 2D fraction, a 3D fraction and a fine particulate fraction and producing them as an output stream, and a ballistic separator (110) an optical sorter (120) connected to the output of the ballast separating the incoming 2D fraction into a positive 2D fraction and a 2D residual fraction and producing them as an output stream, wherein the 3D fraction serving output of the ballistic separator (110) and the positive 2D fraction output of the 2D optical sorter at least one of which is connected to a manual sorting unit.
