The invention relates to a system for the gravimetric sorting of a mixture of substances during the processing and/or the recycling of residual building materials and/or demolition materials, comprising a fractioning unit (2) adapted to divide the mixture of substances into at least m fractions (A, B, C); at least n·m gravimetric densimetric tables (A.1, A.2.2, A.3.2), arranged in m cascades each with at least n densimetric tables distributed to n stages, wherein the fractioning unit is coupled to them densimetric tables (A.1) of the first stage such that a different one of the at least m fractions can be supplied to each of the densimetric tables of the first stage; wherein, within each cascade, each densimetric table of a considered stage (A.2.2, A.3.2) is coupled to a densimetric table (A.1, A.2.2) of the preceding stage such that either the first partial fraction or the second partial fraction (12, 22) of the densimetric table (A.1, A.2.2) of the preceding stage can be supplied to the densimetric table (A.2.2, A.3.2) of the considered stage. An appropriate method is also part of the invention.
