Mechanochemical process

Mechanochemical process for the decontamination and/or elimination of problematic, synthetic, biogenic and biological materials (A), for the digestion of phosphates (B), for the immobilization of metals and their compounds (C), for the splitting of carbon dioxide (D) into the elements and for the recovery of valuable products (E), characterized in that

• (I) one makes available as the ground stock F at least one fluid F, at least one solution F, at least one suspension F, at least one finely divided solid mixture F and/or at least one reactive gas F, containing
• at least one material A, B, C and/or D and
• at least one material G, selected from the group consisting of pure, finely divided, mineral coal, partially pyrolyzed coal, biochar and activated carbon, contaminated or impregnated, finely divided mineral coal, partially pyrolyzed coal, biochar and activated carbon, finely divided lignite and pure and contaminated or impregnated, finely divided carbon suppliers as well as of the above-mentioned, moistened materials G, or alternatively, the components F and G are made available separately from one another,
• (II) one feeds the at least one fluid F, the at least one solution F, the at least one suspension F, the at least one finely divided solid mixture F and/or the at least one reactive gas F continuously or discontinuously into the grinding chamber (1.1) of at least one mechanical mill (1) or alternatively
• (III) one pours the components A, B, C and/or D as well as G of the ground stock F into the grinding chamber (1.1) of the at least one mechanical mill (1) one after the other or at the same time, continuously or discontinuously, and
• (IV) finely grinds them therein with agitation means (1.4) or moving grinding media (1.2) or with rollers (1.4.6) at constant and/or variable speed of rotation, after which one
• (V) separates the resulting at least one suspension H of at least one pulverulent product I and/or the at least one pulverulent product I continuously or discontinuously from the grinding media (1.2) or the rollers (1.4.6) and discharges it from the grinding chamber (1.1) and
• (VI) separates the at least one finely divided, solid product I from the suspension H, as a result of which at least one digested, biologically available, soluble material passes into the liquid medium as product E of value, or
• (VII) one washes out the at least one digested, biologically available, soluble material E present or still present in the at least one finely divided, solid product I with at least one liquid medium or leaves it in the at least one product I as product E until its further use and/or
• (VIII) one recycles the at least one washed, finely divided, solid product I of activated carbon G to process step (I) and/or uses it as product of value E elsewhere and/or
• (IX) one stores the at least one finely divided, solid product I, which contains at least one immobilized metal C and/or at least one compound C thereof, until it is reused as product E of value or disposes it and/or
• (X) one separates the resulting elemental nitrogen and/or oxygen.
