In a sink-float process (high density media segregation), the material to be dressed is conveyed to a rotary drum contg. high density separation medium and both the sedimentary matter and floating matter are discharged from the drum purely mechanically so that the high density medium remains essentially stationary. Used in the sink-float treatment of storage battery scrap, particularly the separation of casing fragments and metallic Pb. The process is carried out in a simple and compact appts. which can accommodate comparatively low throughput capacity. Heavy matter is constantly moved and kept in suspension. No circulation of high density medium is required. Sink-float separation of sedimentary matter and floating matter and the washing of the separated products are carried out in one appts. with a single drive. |
