  A method of treating a mammal for the presence or the activity of H. pylori in the gastrointestinal tract is disclosed. The method encompasses orally administering to said mammal a sufficient amount of a scavenging, reacting or inactivating compound to remove bicarbonate ions, ammonium ions or urea which are present in combination with the microorganisms which colonize and infect the gastric mucosa. Such microorganisms have been implicated in gastritis, gastric ulcer disease and as a risk factor in gastric carcinoma. Also, the invention encompasses a method, utilizing similar compounds, for the treatment or prevention of dermatitis such as diaper rash wherein these compounds are preapplied to the skin or used to treat the diaper prior to use. Also included are compositions which are used for the methods described above.

  Magnesium values are leached from a fragmented mass containing combusted oil shale particles. Magnesium is leached selectively with respect to calcium compounds and silicates with aqueous solutions of a mixture of purgeable, acid-forming gases such as carbon dioxide with a minor proportion of sulfur dioxide. A two-stage leaching process can employ leachant with dissolved carbon dioxide and sulfur dioxide in a first stage and with a carbon dioxide containing solution in the substantial absence of sulfur dioxide in the second stage. An enriched solution containing magnesium values is withdrawn from the fragmented mass and magnesia is recovered from such enriched solution. In one embodiment a fragmented permeable mass of formation particles containing oil shale and carbonates of calcium and magnesium is formed in an in situ oil shale retort. A combustion zone is advanced through the fragmented mass, whereby kerogen in oil shale in the fragmented mass is decomposed in a retorting zone on the advancing side of the combustion zone to produce gaseous and liquid products including shale oil, and particles containing retorted oil shale are combusted for converting magnesium values to more leachable form such as magnesium oxide. Such a process is also used for leaching combusted oil shale from above ground retorting and combustion.

  镁的价值从含有燃烧页岩颗粒的碎片质量中被浸出。镁被有选择性地浸出，相对于钙化合物和硅酸盐，使用一种混合的可净化、酸性气体的水溶液，例如二氧化碳和少量的二氧化硫。两阶段浸出过程可以在第一阶段使用溶解的二氧化碳和二氧化硫的浸出剂，在第二阶段使用含有二氧化碳的溶液，基本上不含二氧化硫。从碎片质量中提取含有镁价值的富集溶液，并从这样的富集溶液中回收氧化镁。在一种实施例中，形成了一个碎裂渗透的地层颗粒质量，其中包含页岩和钙镁碳酸盐，在原位的页岩加热炉中。通过碎片质量中的燃烧区域推进，使得碎片质量中的页岩在炼制区域中分解，产生包括页岩油的气体和液体产品，然后燃烧含有炼制过的页岩的颗粒，以将镁价值转化为更易浸出的形式，例如氧化镁。这样的过程也用于从地面炼制和燃烧的燃烧页岩中浸出。

  A method for recovering a magnesium carbonate of high purity from an aqueous magnesium hydroxide slurry is disclosed. The slurry contains at least 1 percent of magnesium hydroxide and consists of water, magnesium hydroxide and impurities normally associated with magnesium hydroxide slurries. The method involves carbonating the slurry with sufficient carbon dioxide to dissolve a substantial proportion of the magnesium hydroxide therein as magnesium bicarbonate, continuing carbonation until a solution saturated with magnesium bicarbonate is formed, a portion of the magnesium bicarbonate is converted to a crystalline magnesium carbonate and substantially all dissolved calcium is precipitated, so that the slurry contains dissolved magnesium bicarbonate, a crystalline magnesium carbonate precipitate and a calcium carbonate precipitate. Solids are then separated from the magnesium bicarbonate solution, the solution is decarbonated, for example by heat or vacuum, and hydrous magnesium carbonate is separated from the aqueous phase.
