BIOSTIMULANT BASED ON BACTERIA FOR BETTER ADAPTATION OF PLANTS TO HYDRIC AND OSMOTIC STRESSES
Streptomyces acrimyciniStreptomyces mutabilisPolyangiumbrachysporumbrachysporum). This invention also describes a new bacterial inoculum formulation based on the optimisation of certain biological properties in these bacteria (N1, N4 and N3), namely their properties in increasing the water retention capacity of soils and in solubilising and mobilising the forms of potassium for the plant from complex inorganic forms which are not accessible to the plant without the microbial partner thereof (BCD and BSK). By including together propagules of these bacteria and perlite as a matrix, the ability of the (BDC and BSK) to increase the sponge capacity of soils and to solubilise the insoluble forms of potassium and make them accessible to the plant will be increased. As a result, the role of the (BDC and BSK- Plant) partnership on the development of the host plant will be optimised by intimately combining the impact of these bacteria on the plant directly (control of absorption, conduction and transpiration) and indirectly (availability of the water in soils in a uniform manner, by modification of the components that cause water loss by leaching, evaporation).

Processes for the recovery of uranium from wet-process phosphoric acid using dual or single cycle continuous ion exchange approaches
In alternative embodiments, the invention provides processes and methods for the recovery, removal or extracting of, and subsequent purification of uranium from a wet-process phosphoric acid using a continuous ion exchange processing approach, where the uranium is recovered from a phosphoric acid, or a phos-acid feedstock using either a dual or a single stage extraction methodology. In both cases an intermediate ammonium uranyl-tricarbonate solution is formed. In alternative embodiments, in the dual cycle approach, this solution is contacted in a second continuous ion exchange system with a strong anion exchange resin then subsequently recovered as an acidic uranyl solution that is further treated to produce an intermediate uranyl peroxide compound which is ultimately calcined to produce the final uranium oxide product. In alternative embodiments, in the single cycle case, the intermediate ammonium uranyl-tricarbonate solution is evaporated to decompose the ammonium carbonate and produce an intermediate uranium carbonate/oxide solid material. These solids are digested in an acid medium, and then processed in the same manner as the secondary regeneration solution from the dual cycle process to produce an intermediate uranyl peroxide that is calcined to produce a final uranium oxide product.

Processes for the recovery of uranium from industrial phosphoric acid using dual or single cycle continuous ion exchange approaches
In alternative embodiments, the invention provides processes and methods for the recovery, removal or extracting of, and subsequent purification of uranium from a wet-process phosphoric acid using a continuous ion exchange processing approach, where the uranium is recovered from a phosphoric acid, or a phos-acid feedstock using either a dual or a single stage extraction methodology. In both cases an intermediate ammonium uranyl-tricarbonate solution is formed. In alternative embodiments, in the dual cycle approach, this solution is contacted in a second continuous ion exchange system with a strong anion exchange resin then subsequently recovered as an acidic uranyl solution that is further treated to produce an intermediate uranyl peroxide compound which is ultimately calcined to produce the final uranium oxide product. In alternative embodiments, in the single cycle case, the intermediate ammonium uranyl-tricarbonate solution is evaporated to decompose the ammonium carbonate and produce an intermediate uranium carbonate/oxide solid material. These solids are digested in an acid medium, and then processed in the same manner as the secondary regeneration solution from the dual cycle process to produce an intermediate uranyl peroxide that is calcined to produce a final uranium oxide product.

This invention describes the obtaining of a biostimulant based on 3 bacterial strains for boosting plant resistance to hydric and osmotic stresses. These bacteria are capable of increasing the hydric potential of soils by means of the degradation of waxes (BDC) which coat the components of soils and reduce the capacity of the latter to store sufficient rain and/or irrigation water. In addition, these bacteria help plants to save water more successfully via optimal and continual potassium nutrition (BSK). These three bacteria (BDC + BSK) are coded N1, N4 and N3 and identified (N1 = Streptomyces acrimycini N4= Streptomyces mutabilis and N3= Polyangium brachysporum). This invention also describes a new bacterial inoculum formulation based on the optimisation of certain biological properties in these bacteria (N1, N4 and N3), namely their properties in increasing the water retention capacity of soils and in solubilising and mobilising the forms of potassium for the plant from complex inorganic forms which are not accessible to the plant without the microbial partner thereof (BCD and BSK). By including together propagules of these bacteria and perlite as a matrix, the ability of the (BDC and BSK) to increase the sponge capacity of soils and to solubilise the insoluble forms of potassium and make them accessible to the plant will be increased. As a result, the role of the (BDC and BSK- Plant) partnership on the development of the host plant will be optimised by intimately combining the impact of these bacteria on the plant directly (control of absorption, conduction and transpiration) and indirectly (availability of the water in soils in a uniform manner, by modification of the components that cause water loss by leaching, evaporation).
The present invention relates to an integrated method for the decadmiation of phosphoric acid, which comprises: etching (1) phosphate (Ph) with sulphuric acid (SA) in a reactor so as to prepare a phosphoric acid solution containing cadmium and calcium sulphate dihydrate or hemihydrate; concentrating (2) said phosphoric acid solution, so as to form a concentrated phosphoric acid (PA) having a mass content between 42% and 61% of P2O5; adding (3) sulphuric acid (SA) in order to adjust the free sulphate content, anhydrite being formed by recrystallisation of the calcium sulphate dihydrate and hemihydrate, the cadmium co-crystallising with said anhydrite, so as to obtain decadmiated phosphoric acid and cadium-rich anhydrite sludge; - desulphating (4) the decadmiated phosphoric acid; desaturating (5) and clarifying (6) by decanting the mixture of decadmiated phosphoric acid and sludge; conditioning (7) said sludges (PS1) with a phosphoric acid solution (APd) having a titre by mass of less than or equal to 61% of P2O5; recycling the conditioned sludge (PS2) in the phosphate etching step (1).
