NOVELTY - Washed mixture (3) is separated in two step process. Polypropylene (7) is removed from the mixture (3) before, between or after the separation stages (8, 9) by means of a float sink separator (6).    USE - Used for recycling used lead accumulators.    ADVANTAGE - Separation effectiveness and economy are improved. Throughput rates are increased.    DETAILED DESCRIPTION - Separation of the constituents of the mixture (3) resulting from comminution of accumulator materials takes place by washers (8, 9), with the mixture delivered to a first separation stage (8) with or without classification and/or with or without preliminary sorting. The first separation stage comprises separating lead bearing constituents from plastics (14) or from lead plastic constituents (13). The second separation stage (9) comprises separating lead plastic constituents from plastics. Polypropylene (7) is removed from the mixture (3) before, between or after the separation stages (8, 9) by means of a float sink separator (6).    Preferred Features: Extractor units and/or washers are used for separation of the material mixture (3). The material mixture is classified before the first separation stage, with subsequent separation of paste and fine lead particles from plastic constituents which have passed through the classification sieve. Alternatively the mixture is delivered to the first separation stage without classification. At the first separation stage paste, fine lead particles, and piece lead are separated from lead-plastic and plastic constituents. Paste and fine lead particles are extracted as barrel material from the washer (8). Paste and fine lead particles are classified before or after the first separation stage by means of a sieve unit. After classification the material mixture (3) is divided into heavy and light materials, and subsequently processed separately. Lead plastic constituents (13) after the second separation stage (9) are routed back to the last comminution stage (2).
