摘要： In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘undercut’, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.
摘要翻译：特别是含有天然碱的矿床的原位溶液开采方法，其包括将在矿石钻出的钻孔内的矿石区域暴露于溶剂，并将期望的溶质溶解在暴露的区域内以提供液体并产生空隙的“ 底切“，这种底切使得矿石易于引力加载和破碎。未发现的矿石通过重力落入底切而不破坏矿顶，导致新鲜矿石暴露于溶剂中并防止溶剂暴露于屋顶附近的污染物质。期望的溶质最终从其地板直到其顶部溶解在整个床中。溶剂注射可以通过位于钻孔内部的导管输送，并且可以通过缩回或穿孔导管来移动。该方法可以采用推进的底切启动的向上倾斜和行进下倾，或者采用后退的底切开始向下倾斜和向上移动。

摘要： A particulate sodium bicarbonate product with an excellent flowability characterized by an angle of repose less than 30 degrees. An angle of repose of less than 27.5 is particularly good. The product is preferably in the form of ovoid or spherical particles, in that the particles have a mean axial ratio of at least 0.5. In some embodiments, the sodium bicarbonate product has a smooth particle surface in which less than 75% of the particle surface is covered with spikes. The particles may have a mean diameter D50 of at least 75 microns but less than 300 microns. The particulate sodium bicarbonate product comprises inorganic and organic impurities embedded in its polycrystalline structure, for example at least 75 ppm TOC; or at least 30 ppm Ca; or from 1 to 18 ppm Mg; or more than 0.6 g/kg NaCl; and/or from 100 to less than 500 ppm Si. A process for manufacturing such product, and its use for the treatment of pollutants in gases such as removal of acid gas.

摘要： A process for the joint production of crystalline sodium bicarbonate and another alkali compound, in which the step for producing such alkali compound generates CO2 as a byproduct, at least a portion of which is used as a feed to the sodium bicarbonate production step. The produced alkali compound is preferably crystalline sodium sulfite. The joint production process preferably employs as feedstock one or more sodium carbonate liquors derived from trona ore. A gas feed which contains CO2 byproduct is subjected to a gas treatment which may include water removal and/or compression before it is used to produce sodium bicarbonate crystals from a sodium carbonate liquor. Such gas feed may comprise a reactor offgas exiting a sulfite reactor; a vent gas exiting a feed or surge tank; a decarbonation gas exiting a decarbonation unit; a vent gas vented from a crystallizer heater; or combinations of two or more thereof.
