Abstract: FIELD: plastic metal working, possibly manufacture of three-dimension products of sheet blanks. SUBSTANCE: method comprises steps of feeding blanks of sheet material one after another in apparatus for imparting them round shape by plastically deforming them along circle arc by rounding until achieving desired constant radius. Portion of blank leaving rounding apparatus in position of rounding is deflected by means of guides while it is elastically deformed for shifting it to transporting position from rounding position and in the result above mentioned portion of elastically deformed blank is held under load. As soon as end portion of blank leaves rounding apparatus it jumps to transporting position by action of said load and sets free path for next blank of sheet material that also may be subjected to rounding deformation but only after previous rounded blank of sheet material is knocked out of said apparatus for further transportation.

Abstract: FIELD: hydrometallurgy. SUBSTANCE: invention consists in extraction of tributyl phosphate from aqueous solutions with regeneration of tributyl phosphate and extractant. For extraction, nonpolar organic solvent is used, and isolation of tributyl phosphate from extracts is effected via "three-phase" reextraction process consisting in isolation from organic solvent of low-soluble liquid phase of tributyl phosphate compounds with sulfuric acid, ferric chloride or with ferric chloride-hydrochloric acid complex salt. After separation of three-phase system, tributyl phosphate-free light-weight hydrocarbon phase is directed into tributyl phosphate extraction stage; aqueous solution replenished with reextracting substance (sulfuric acid, ferric chloride, or ferric chloride-hydrochloric acid mixture) is used to reextract tributyl phosphate; and heavy organic phase containing tributyl phosphate salts is washed out with water from inorganic acids and salts to produce tributyl phosphate and dilute aqueous reextracting solution. Aqueous reextract, when evaporated, is used to replenish reextracting solution. EFFECT: enabled return of tributyl phosphate into main extraction cycle. 2 ex
