1. A fluidized bed separator (1) comprising a body wall (10) defining:
a fluidizing section (7) having a fluidization fluid distribution chamber (25) and at least one fluidization fluid inlet (9) for introducing fluidization fluid into the fluidization fluid distribution chamber (25), the fluidizing section (7) comprising an upper panel equipped with a plurality of fluidization outlets (26);
a main separation chamber (6) above the fluidizing section (7) for establishing a fluidized bed within the main separation chamber (6) by virtue of fluidization fluid exiting the fluidization fluid distribution chamber (25) through the fluidization outlets (26) and entering into the main separation chamber (6); and
an upper separation chamber (19) above the main separation chamber (6) comprising a plurality of inclined plates (17), channels (18) defined between the inclined plates (17); and one or more launders (15) feeding a collection basin (21);
the fluidized bed separator (1) further comprising a feed section (4) below the upper separation chamber (19) and above the main separation chamber (6), the feed section (4) comprising one or more feed pipes (11) extending substantially horizontally and transversely through the body wall (10) and into the feed section (4); the one or more feed pipes (11) being positioned lower than or below the inclined plates (17);
wherein the one or more feed pipes (11) comprise a plurality of outlets (23) which are each configured to introduce feed slurry comprising solids into the feed section (4) in a generally horizontal direction which is generally transverse to a vertical axis of the fluidized bed separator (1), such that the one or more feed pipes (11) are configured to distribute the feed slurry across the feed section (4) and toward the body wall (10) or toward an inner perimeter of the feed section (4), wherein the plurality of outlets (23) are also positioned lower than or below the inclined plates (17).
