摘要： A method for processing bauxites according to the Bayer technology, with an increased yield in Al.sub.2 O.sub.3 and with decreased caustic soda losses, starting particularly from goethite bauxites of boehmite and/or diaspore type and carrying out the digestion at 180.degree.C to 300.degree.C using an aluminate liquor containing Na.sub.2 O.sub.caustic in a concentration of 80 to 300 g./l. The digestion is carried out in the presence of a calcium compound in an amount corresponding to 2 to 6 % of CaO calculated for the dry weight of bauxite and of a sulfate salt in an amount corresponding to 1.0 to 7.0 g./l. of sulfate ion concentration, whereby the goethite content of the bauxite is converted into hematite. The process provides advantageous conditions for the complete dissolution of the boehmite and diaspore content of bauxite in the vicinity of the equilibrium molar ratio, and enables to recover efficiently the caustic soda losses in the Bayer process itself, requiring no supplementary operation.
摘要翻译：根据拜耳技术处理铝土矿的方法，特别是从勃姆石和/或水泥浆类型的针铁矿铝土矿开始，Al2O3的产率提高，苛性钠损失降低，并在180℃至300℃下进行消化，使用含有浓度为80至300g / l的Na2O8的铝酸盐液体。在钙铝化合物的存在下进行消化，钙化合物的量相当于铝土矿的干重量和对应于1.0至7.0g / l的硫酸盐的2至6％的CaO。的硫酸根离子浓度，由此将铝土矿的针铁矿含量转化为赤铁矿。该方法提供了在平衡摩尔比附近完全溶解勃姆石和铝土矿的含量的有利条件，并且能够有效地回收拜耳法本身的苛性钠损失，不需要补充操作。

摘要： An improved process for accelerating the digestion process in the Bayer alumina process is provided which promotes both the goethite-hematite conversion and a more perfect and quick dissolution of the diaspore. The above is achieved by carrying out the digestion in the process of 5-20% by weight calculated on the dry weight of the bauxite of a novel hydrogarnet catalyst.

摘要： In a method of and a compression tube (10) for increasing pressure of a flowing gaseous medium the gaseous medium is pressed by an accelerating element (8) to flow with supersonic velocity. Heat is abstracted from the gaseous medium having supersonic velocity and by shock waves the flow is decelerated to a subsonic velocity range in an impact tube section (13) wherein by decelerating and, if necessary, further abstracting heat the pressure is increased. The power machine comprises in any pipeline section and/or instead of compressor a compression tube (10) including the accelerating element (8), a transient tube section (14) receiving supersonic flow of the gaseous medium, an impact tube section (13) comprising a shock wave tube section (12) and advantageously a passage tube section (16) for decelerating the supersonic flow to subsonic velocity and increasing the pressure to a value exceeding the inlet pressure of the accelerating element (8).
