摘要： A process for the selective recovery of cadmium, molybdenum, zinc, nickel and other metal values from wet process phosphoric acid and other acidic to slightly basic carrier solutions, wherein the metal-bearing solution is contacted with an organophosphene extractant to precipitate the metal values for subsequent separation from the solution. Separation may be effected by mechanical means or by scrubbing with a water-immiscible organic solvent such as kerosene for subsequent recovery of the metal values. The metal specie recovered is determined by the concentration of the organophosphene, which may be selectively adjusted to recover a series of metal values in a sequence of stages.

摘要： A process for beneficiating phosphate containing ores, wherein promoter reagents are added to the ore slurry prior to the addition of collectors and depressants for flotation of the carbonate and silica components. The promoters aid in increasing the rejection of the magnesium present during carbonate and silica flotation steps and recovery of phosphates, so that acceptably low magnesium levels for phosphoric acid production can be achieved in a phosphate concentrate in a single rougher stage. Preferred promoters include sodium carbonate and ammonium hydroxide.
摘要翻译： 一种用于选择含磷矿石的方法，其中在添加用于浮选碳酸盐和二氧化硅组分的收集剂和抑制剂之前，将催化剂试剂加入到矿浆中。 助催化剂有助于增加碳酸盐和二氧化硅浮选步骤中镁存在的排斥反应并回收磷酸盐，从而可以在单一粗化阶段的磷酸盐浓缩物中实现磷酸生产的可接受的低镁含量。 优选的助催化剂包括碳酸钠和氢氧化铵。
