| 20100322831 | METHOD FOR THE PRODUCTION OF METAL PRODUCTS - The invention provides a method for the Industrial purification of a low-grade polyvalent cation feed stream of purity P1, by the formation of a polyvalent cation-double-salt precipitate of purity P2 and a polyvalent cation solution with purity P3, wherein P2>P1>P3, said method comprising the steps of: a) forming, from said feed, a medium comprising water, polyvalent cation, a cation selected from the group consisting of ammonium, cations of alkali metals, protons and a combination thereof, and anions; which formed medium is further characterized by the presence of (i) a double-salt precipitate comprising a polyvalent cation, at least one of said cations and at least one of said anions; and (ii) a polyvalent cation solution; and wherein the concentration of said anions is higher then 10% and the ratio between the concentrations of said cation to said anion in said polyvalent cation solution is within Zone DS as herein defined; and b) separating at least a portion of said precipitate from said solution. | 12-23-2010 |
| 20100291646 | Process for the Recovery of a Fermentation Product - The present invention provides a process for the purification and concentration of a partially water-soluble organic product from a source containing the same at concentration C0, which process comprises the steps of: (i) concentrating said product by means of a resin to form a first aqueous solution at concentration of C1; and (ii) fractionating an aqueous solution by temperature adjustment to form a second aqueous solution and a third aqueous solution with concentrations C2 and C3, respectively, wherein C2>C3 and C2>C1>C0. | 11-18-2010 |
| 20100257977 | PROCESS FOR THE PRODUCTION OF TITANIUM SALTS - The present invention provides a method for the Industrial production of a titanium salt TP, said method comprising the steps of: i. Precipitation of titanic acid from a solution comprising titanium salt TP1; ii. Production of a titanium containing product TP2 from a medium comprising of said titanic acid and an acid; and iii. Thermal conversion of titanium containing product TP3 to a titanium salt TP at temperature higher than 17O° C. | 10-14-2010 |
