摘要:
The invention relates to a method for processing cadmiferous solids that contain anhydrite and/or hemihydrate calcium sulphate having a cadmium content, characetrised in that it comprises extracting the cadmium from said cadmiferous solids by putting them in contact with an aqueous solution of an alkaline metal, and carrying a solid/liquid separation between a solid phase containing dihydrate calcium sulphate with a low cadmium content relative to said cadmium content in the anhydrite and/or hemihydrate calcium sulphate, and an aqueous phase containing alkaline metal sulphate and cadmium in a solution.

The present invention relates to a capsule 102 containing dry infusible matter 101 for preparing infused beverages, and comprising: a front face 103 comprising a filter wall 114; a rim 105 surrounding said front face 103 and presenting a tapered outer edge 108; a back face 104, substantially opposed to said front face 103, and comprising a frangible region 116 for the injection of infusing liquid; and a solid envelope 106 between said rim 105 and said back face 104. The present invention also relates to a device 120 for preparing infused beverages comprising: said capsule 102, with the front face 103 in a substantially vertical position; and injecting means 124 for introducing an infusing liquid into said capsule 102 through said frangible region 116 when said capsule 102 is in said receptacle 118; and an infusion vessel 123 with a substantially vertical side opening 125 to said receptacle 118, so as to be in fluid connection with said filter wall 114 of the capsule 102 when said capsule 102 is in said receptacle 118, and an openable and closable bottom opening 127 to allow an infused beverage to flow out of the infusion vessel 123. Finally, the present invention also relates to a method of preparing infused beverages using said capsule 102 and device 120.

摘要:
Method for producing hydrometallurgical zinc oxide powder having characteristics equivalent to that derived from a French process, comprising formation of an aqueous pulp from a starting zinc oxide having particles of nodular structure, wet milling of this aqueous pulp, separation in this milled pulp between a liquid phase and a solid phase containing the zinc oxide, and drying of said solid phase, coupled with a mechanical deagglomeration of the particles during drying, to obtain a dry zinc oxide powder with particles of nodular structure having a particle size distribution where the particles have an average size (d50) between 0.02 and 20 µm.
