Title: Improvements in or relating to machines for recovering precious metals
Filed: 1923-12-03
Abstract: 212,208. Rousseau, G. E. C. Dec. 3, 1923. Density separators.-A gold-washing machine has centrifugal separating mechanism which can be reciprocated while it is rotating, and means for causing a flow of water against the normal discharge flow of the gold to prevent any foreign matter from escaping with the gold. An inverted cone 33 is secured to a spider 34 on the shaft 20, and just above the cone is fixed a conical member 41 with an outwardly directed flange 57. Outside this flange is a wire screen ring 37 carried by brackets 36. The cone 33 rotates inside a cone 29 with collecting rings 26, 30. The. driving pulley 46 is attached to the shaft to permit relative axial movement; the shaft also carries a hub 50 to which is attached the rim 52 resting on tapered rollers 55 which work over a series of ratchet notches 54 in the ring 53. As the apparatus rotates, the rollers impart a reciprocating axial movement to the shaft, causing a jarring action on the material. The pulp is fed into the hopper 40 and travels over the flange 57. The gold particles pass through the screen ring 37 to the collector 26 and discharge 27, while the foreign matter passes to the collector 30 and discharge 31. Water is supplied through the pipe 24 and flows upwards to assist in carrying off the foreign matter. Packing 21 round the lower end of the shaft is held in place by a cap 22 on the boss 19. Each time the shaft rises, water is drawn in through an opening 19<1> in the boss, and this acts as a cushion for the reciprocating means.

Abstract: 666,781. Purifying sugar solutions. AKTIEBOLAGET SEPARATOR. Nov. 26, 1948 [Nov. 26, 1947], No. 30726/48. Class 127. [Also in Group II] Sugar juices are purified by adding chemicals to change their pH and precipitate organic impurities, filtering with filter aids which with the impurities, both organic and inorganic, form a sludge which is removed from the juices, removing the main part of the organic impurities from the sludge in a centrifuge and returning the treated sludge wholly or in part for reuse. In operation, sugar beets are washed, sliced and the slices treated with counterflowing liquid in a diffusor batterv 3-7. The slices are strained in a device 8 the water therefrom being returned to the diffusor battery. The slices are pulped in a press 9, the expressed liquid treated with acid and passed to a sedimentation apparatus 11- the separated water being also returned to the diffusors. The sludge is concentrated in a separator 12 and transferred to a drier 10 wherein the pulp from the press 9 is also dried. The raw sugar juice leaves the diffusor 3 and is treated with lime in a container 13 for optimal precipitation. A further lime treatment is given in a container 14 and then followed by a carbon dioxide treatment whereby calcium carbonate is precipitated into the organic impurities precipitated in the container 13. Separation of the juice from the precipitate is effected in separators 16 or 16a, but the separated juice is further treated with carbon dioxide in a container 17 to precipitate more lime, and passed to a filter 18. The sludge so obtained is mixed in a mixer 19 with that from the separators and filtered in a filter 20. The juice therefrom mixes with the juice from the filter 18 is saturated with carbon dioxide in a container 21 to precipitate the remaining lime and filtered on a filter 22, the juice thereby obtained being suitable for concentration by evaporation. The sludge obtained from this filter 22 is returned to the mixer 19 and serves as a filter aid in the filter 20. The sludge from the filter 20 is mixed with water and fed to the centrifugal separator 23 in which the filter aid is separated from the organic impurities and returned to the mixer 19. This organic component is returned to the sedimentation apparatus 11.
