摘要： A process for obtaining pure orthophosphoric acid from superphosphoric acid is provided comprising:(a) hydrolyzing superphosphoric acid with water until a mixture of polyphosphoric acids and orthophosphoric acid is formed, wherein the total P.sub.2 O.sub.5 content of said mixture is from 65% to 70% and the poly P.sub.2 O.sub.5 content of said mixture is from 1% to 15% of the total P.sub.2 O.sub.5 ;(b) crystallizing said orthophosphoric acid from said mixture;(c) separating said orthophosphoric acid from said mixture; and(d) washing said orthophosphoric acid with an organic solvent having a low or limited solubility for orthophosphoric acid.

摘要： Solution mining method particularly adapted for recovery of potash and the like from relatively thin, inclined strata at substantial depths and involving the dissolution of ore strata, overlain by insoluble strata, while leaving the remainder of the formation in place. Water is injected down a bore hole at a predetermined rate and, being much less dense than present brine, flows in an updip direction along the top of the cavity to a forward mining face remote from the drill hole. Loaded, heavy brine flows downdip along the bottom of the stratum to an outflow pipe communicating with the bottom of the bore hole.

摘要： An apparatus and method for spray metallizing a coating of metal (e.g., zinc) onto one or both sides of a base metal (e.g. steel). One embodiment of the invention comprises melting the metal to be deposited, propelling first and second streams of the melted metal towards the base metal at a point of convergence adjacent to the substrate, and applying a potential difference between the streams to form an electric arc whereby superheated particles are deposited on the base metal. A second embodiment of the invention comprises melting the metal to be deposited, propelling a stream of the melted metal towards the base metal through a nozzle containing a non-consumable stationary electrode, and applying a potential difference between the molten metal and the electrode to form an electric arc whereby superheated particles are deposited on the base metal.

摘要： A method of mining substantially horizontal beds of trona ore, such as are found in the vicinity of the town of Green River, Wyoming, in which substantially all the ore within a given area is extracted. Mining is accomplished by driving substantially parallel entries into the trona formation approximately 100 to 200 feet apart, connecting the entries by at least one primary passage which thereby defines a trona panel, supporting the roof of the primary passage by movable roof supporting structures, and mining the exposed short face or wall of the trona panel. The mined material is removed and the roof supporting structures are advanced so that the structures remain essentially adjacent and parallel to the panel face being mined as it recedes. The roof supporting structures are continuously advanced incrementally to effect caving of the previously supported roof and facilitate mining of the exposed short face of the trona panel.
