摘要： To prepare a mixture of sodium silicates having lamellar structure and sodium carbonate peroxohydrate, sodium silicate composed essentially of .delta.-Na.sub.2 Si.sub.2 O.sub.5 is reacted at least partially with carbon dioxide and atomized water with continuous circulation with the formation of a kanemite/sodium hydrogen carbonate mixture. The kanemite/sodium hydrogen carbonate mixture and further sodium silicate composed essentially of .delta.-Na.sub.2 Si.sub.2 O.sub.5 is brought into contact with atomized water with continuous circulation. Finally, 0.015 to 1.5 mol of hydrogen peroxide per mole of sodium silicate composed essentially of .delta.-Na.sub.2 Si.sub.2 O.sub.5 employed is added to the resulting kanemite/sodium carbonate mixture.

C. and pressures of 10 to 30 bar. This water glass solution having at least 20% by weight of solids is treated in a spray drier with hot air at 200.degree. to 300.degree. C. with the formation of a pulverulent amorphous sodium disilicate having a water content (determined as loss on heating at 700.degree. C.) of 15 to 23% by weight and a bulk density of at least 300 g/l. The spray-dried pulverulent, amorphous sodium disilicate is ground.

摘要： For working up concentrated, preferably partially condensed phosphoric acid which is contaminated with organic components, the phosphoric acid is first thoroughly mixed with fine-grained sand in a weight ratio of (0.5 to 1.5):1. Then, to neutralize the mixture, a basic, oxygen-containing calcium compound is added, while the thorough mixing is continued, until a 10% aqueous suspension of the mixture to which the calcium compound has been added has a pH between 5 and 11. Finally, the mixture which contains the calcium compound is commminuted after cooling.

摘要： The present invention relates to a process for recovering uranium from raffinate which is obtained by extracting phosphoric acid from a uranium-containing wet-process phosphoric acid with the aid of organic extractants and separating the resulting organic phosphoric acid extract from residue not taken up by the extract. To this end, the raffinate residue is subjected to thermal treatment and thereby freed from dissolved or emulsified residual extractant. Next, the raffinate is treated with a water-immiscible solvent to extract the uranium, and the extracted uranium is separated from the undissolved raffinate portion.
