  • Patent number: 6086159
    Abstract: Slurryable ore where the overburden is unstable and subject to collapse is mined from substantially parallel elongated main trenches connected by a perpendicular trench at the bottom of the mineral seam. A plurality of softwall mining devices supported by face equipment is placed in the perpendicular trench. The devices slurry the mineral material and move into the mineral seam as the overburden sloughs behind the mining devices. The subsided overburden is supplemented as necessary with injected material. Slurried mineral flows to the parallel trenches for removal to the surface. After the softwall devices have advanced the length of the parallel trenches, the devices are withdrawn and placed in additionally developed trenches elsewhere in the ore reserve.

  • Patent number: 5738787
    Abstract: The present invention features a filtration plate for use in a filter pan comprising a corrugated sheet having a series of alternately upwardly and downwardly opening channels and a reinforcing material bonded to surfaces of the downwardly opening channels. The reinforcing material is effective for strengthening the sheet and retaining heat in a manner effective to slow cooling of the filtration plate during washing and to reduce heat losses from the filtration plate during filtering. According to a preferred aspect of the invention, the corrugated sheet is a monolithic sheet of structural metal having a smooth upper filtration surface. The invention also provides a filter pan configured for use in filtration of a filtrate from solid particles. The filter pan comprises a filtration plate including a corrugated, monolithic sheet of structural metal having a series of alternately upwardly and downwardly opening channels.

  • Patent number: 5698003
    Abstract: Improved solvent systems for the formulation of N-alkyl thiophosphoric triamide urease inhibitors. These formulations enable the preparation of stable concentrated solutions of N-alkyl thiophosphoric triamides for storage, transportation, and eventual impregnation onto solid urea containing fertilizers and incorporation into liquid urea containing fertilizer compositions. These formulations are comprised primarily of a solvent selected from the group consisting of glycols and glycol derivatives. Optionally, in addition to the glycol base solvent, the formulations can contain a co-solvent selected from the group consisting of liquid amides, 2-pyrrolidone and N-alkyl 2-pyrrolidones, and/or a nonionic surfactant selected from the group consisting of alkylaryl polyether alcohols. The presence of the co-solvent and/or surfactant has been found to impart desirable properties to the formulations under certain conditions.

  • Patent number: 4485078
    Abstract: Phosphoric acid is produced by the wet process from phosphate rock containing fluochlorapatite. The rock is ground in a crusher (10) to a size such that from about 50% to about 90% by weight will be passed by a -200 mesh U.S.S. sieve before being passed into a digestor (14) where it is mixed with sulfuric acid and recycled phosphoric acid to form a slurry. A suitable reductant such as sulphur dioxide is added to the slurry to maintain the oxidation-reduction potential in the range from about +150 mv to about +750 mv. The gypsum by-products are then removed from the slurry at filter (16) and a portion of the acid is recycled to digestor (14). The remaining acid is either concentrated and further processed to make fertilizers or is further processed via path (20) to remove aluminum and/or iron impurities. Select amounts of fluoride and sodium containing compounds are added to the acid in a stirred reactor (30) to cause precipitation of aluminum, principally as Na.sub.2 AlF.sub.5.

  • Patent number: 4472368
    Abstract: An economical process for treating the acidic pond water to be used in the internal grinding circuit of a wet process phosphoric acid plant. Water is added to a quantity of a hydratable calcium compound, such as quicklime, to form a slaked lime slurry. A sufficient quantity of the slaked lime slurry is reacted with the acidic pond water to obtain a low fluoride solution having a fluoride content less than about 300 ppm and a pH in the range from about 2.0 to about 3.0, preferentially in the range 2.6-2.8, whereby calcium fluoride is precipitated. The precipitate bearing low fluoride solution is then clarified and the precipitate removed as underflow from the clarifier and transferred to the gypsum pond. In the preferred embodiment, the clarified low fluoride water is fed to the ball mill and is mixed with the phosphate rock being crushed.

  • Patent number: 4439407
    Abstract: A process for the improved filterability of wet process phosphoric acid which comprises maintaining the ratio of ferric ion to ferrous ion in the wet process phosphoric acid above about 1.0 when the total iron concentration of the product wet process phosphoric acid is in the range of from about 0.5% Fe to about 0.9% Fe. The ratio of ferric ion to ferrous ion may be controlled by controlling the temperature in the final stage of a multi-stage calcining process, addition of iron in the form of a compound which yields ferric ion upon dissolution, the oxidation of the iron in the wet process phosphoric acid, or a combination of the above.
