| abstract | 1478851 Treating ball clay ENGLISH CLAYS LOVERING POCHIN & CO Ltd 30 Sept 1974 [11 Oct 1973] 47635/73 Heading C1A The properties of a ball clay are improved by suspending the raw ball clay in water to form a suspension of solids content not greater than 55% by weight, subjecting the aqueous suspension thus formed to a beneficiation operation in order to remove undesirable impurities, thickening the aqueous suspension of beneflciated ball clay in an apparatus which is equipped with means for discharging a thickened, solid-containing material to produce a dewatered beneficiated ball clay of solids content at least 50% by weight and drying the dewatered beneficiated ball clay. The starting suspension suitably contains 30 to 55% by weight of the raw ball clay and suitably contains a deflocculating agent, e.g. a water-soluble salt of a polysilicic acid or polyacrylic acid, a water-soluble condensed phosphate or a copolymeric deflocculant as described in Specification 1,414,964. The beneficiation operation may comprise wet sieving, particle size separation by means of gravitional or centrifugal sedimentation, magnetic separation or froth floatation or a combination of two or more of these techniques. The aqueous suspension of beneficiated ball clay may be thickened in a knife discharge clarifier or a mechanical conveyer centrifuge. When the beneficiation operation is performed in the chemically deflocculated state, a flocculant must be added to the suspension before thickening, e.g. dilute mineral acids, water soluble salts which include polyvalent cations and long chain organic flocculants. The dewatered beneficiated ball clay may be extruded, pelletized or shredded before being dried in a rotary, turbo-tray, fluidized bed or apron dryer. |
