泡沫浮选已广泛地用于各种金属和非金属矿石的精选。在过去的二十年间,美国用浮选法处理的物料量以每年7.4%的速率增长着,日处理总量达到180万吨。过去浮选法主要用来选别硫化矿物,而目前,在美国有一半以上的工厂在浮选非硫化矿物。在这方面,浮选已成功地用于选别各种金矿石,例如,含有黄铁矿、毒砂的矿石和含游离金的矿石。浮选金矿石 Froth flotation has been widely used in the selection of various types of metal and non-metallic ores. Over the past two decades, the U.S. flotation process has grown at a rate of 7.4% a year, bringing the total daily processing volume to 1.8 million tons. In the past, the flotation method was mainly used to classify sulphide minerals. At present, more than half of the plants in the U.S. are flotation of non-sulphurous minerals. In this regard, flotation has been used successfully to sort out various gold ores, for example, ores containing pyrite, arsenopyrite and ores containing free gold. Flotation gold ore
