摘要： A method of aerating a liquid comprising the steps of providing a column, introducing liquid under pressure into an upper zone of the column in the form of a jet of liquid directed in a path, permitting gas to be entrained by the jet of liquid, obstructing the path of the jet of liquid to form a zone of turbulence in which bubbles are formed in the liquid to create a foam or froth bed in the column, and removing the foam or froth.

摘要： A method and apparatus for separating particulate material. The method includes the steps of delivering a substantially constant supply of feed to a first aerator, aerating the substantially constant supply of feed in the first aerator, introducing the substantially constant supply of aerated feed to a flotation vessel below a froth/liquid interface within the vessel, so that floatable particulate material entrained by air bubbles from the first aerator can float upwardly to the froth/liquid interface. Air is introduced into the liquid phase in the flotation vessel via a second aerator located below the level at which the aerated feed is introduced into the flotation vessel, so that floatable particulate material not entrained by air bubbles from the first aerator, may be entrained by air bubbles from the second aerator, as the air bubbles from the second aerator rise upwardly through the liquid phase to the froth/liquid interface.
摘要翻译：一种用于分离颗粒材料的方法和装置。该方法包括以下步骤：向第一曝气器输送基本上恒定的进料供应，对第一曝气器中基本上恒定的进料供应进行充气，将充气进料的基本上恒定的供应引入到泡沫/液体界面下方的浮选槽内容器，使得来自第一曝气器的气泡携带的可漂浮的颗粒物质可以向上浮动到泡沫/液体界面。空气通过第二曝气器被引入浮选槽中的液相中，该第二曝气器位于将充气进料引入浮选槽内的水平面以下，使得不会被来自第一曝气器的气泡夹带的可漂浮的颗粒物质可被夹带来自第二曝气器的气泡，因为来自第二曝气器的气泡向上流过液相到泡沫/液体界面。
