Abstract
A separating apparatus for the sink and float separation of a mineral raw material according to density using a liquid. The separating apparatus includes a rotatable drum including a plurality of sink-product pockets for discharging a sink product of the mineral raw material. The apparatus also includes a raw material inlet for delivering the raw material into the liquid bath, a first liquid inlet and first liquid outlet including an overflow disposed at a top level of the liquid bath, and a second liquid inlet and second liquid outlet. The separating apparatus also includes a front deflecting barrier and a rear deflecting barrier, each projecting into the liquid bath from above and disposed over an entire width of the liquid bath. In addition, a method for the sink and float separation according to density of a mineral raw material using a liquid.
