Sorting is by means of a pneumatic table (8) (sic), and the material can be graded before sorting, preferably by sifting (7). Mineral portions rolling downwards from the sieve overflow can be separated, preferably by an inclined conveyor belt (9). The fraction of greater specific gravity can be disintegrated, preferably selectively and by impact-, hammer- or roller-crushing, and the sieve passage can be washed out. |
