Title: Improvements in or relating to apparatus for filtering dust laden gases
IPC: B01D46/32
Filed: 1924-09-18
Abstract: 243,117. Thomson, T., and Nisbet, N. Sept. 18, 1924. Filtering. - Gases are filtered in stages of increasing fineness by passage through successive portions of the same moving bed or diaphragm composed of granular or coarselypowdered material, each passage of the gas being in the same direction through a portion of the same diaphragm nearer to its point of entry to the filtering chamber than the succeeding one, and the stages being kept separate; the increasing fineness of the filtration is due to the deposition in the filter of dust from the gases. The filtering medium falls by gravity between pervious supports 2 disposed within the filtering chamber, which is divided into compartments 3, 4 by a diaphragm 5 having an extension 18 which prevents the passing of the gas between the compartments. A screw 8 or other extractor regulates the flow of the medium and passes it to a screen 10, where it is cleaned, the dust falling into a hopper 11 and the cleaned medium being conveyed back to the inlet 14. Gas passes through the medium in the upper compartment 3 to the conduit 16, leading it outside the filter chamber to the lower compartment, where it traverses the medium escaping at the main 17. The partition 5 may slope down towards the filtering layer as shown, in order to conduct back any escaping filtering medium; or it may slope reversely, the escaping medium being removed by a trap. The filter may be formed as a vertical flat or annular wall, or a wall sloping at the natural angle of repose of the material; two layers may be juxtaposed; or the medium may be carried horizontally on an endless band.

Title: Process for the recovery of uranium
IPC: C01G43/00
Filed: 1958-07-11
Abstract: Uranium values are recovered from slags derived from the reduction of phosphates in the presence of silica, by subjecting to acid attack so that the calcareous constituents are dissolved, leaving the uranium in the solid residue from which it can be extracted.  The slag is ground so that all of it can pass through a Tyler 150 mesh screen and is diluted with an approximately equal weight of water.  Acid is added to the agitated pulp, local concentrations of acid being avoided by successive small additions or slow continuous addition. The acid may be hydrochloric, nitric, perchloric or phosphoric.  The uranium content in the solid residue may be recovered by conventional attack with sulphuric acid or sodium carbonate, or it may be re-used as part the charge to the phosphorus reduction furnace so as to enrich the silica slag with respect to uranium.ALSO:A process for the recovery of uranium wherein slags derived from the reduction of phosphates in the presence of silica are subjected to a mode of acid attack such that the calcareous constituents are dissolved while leaving the uranium in a solid residue from which the uranium can be extracted.  The slag is ground so that all of it can pass through a Tyler 150 mesh screen and is diluted with an approximately equal weight of water.  Acid is added to the agitated pulp, local concentrations of acid being avoided by successive small additions or slow continuous addition.  The acid may be hydrochloric, nitric, perchloric or phosphoric, the latter being included at the rate of 5-15 litres per ton of slag if another acid is used when a low content of P2O5 in the slag could cause serious risk of the calcium salt produced being discoloured by ferric ions.  The strength of the acid used is 5-6 N and the attack lasts at least one hour, the temperature being maintained at 70-80 DEG C., and the final pH of the pulp being 2-3.  The precipitate from the reaction is washed in counter-current using 6-8 cubic meters of water per ton of slag.  The uranium content in the solid residue may be recovered by conventional attack with sulphuric acid or sodium carbonate, or it may be re-used as part the charge to the phosphorus reduction furnace so as to enrich the silica slag with respect to uranium. p
