近几年来,苏联发展了一种称为“泡沫分选”的新选矿方法,并已在工业上应用。这种方法是以矿物表面有选择的可润湿性为依据。由于固体颗粒与气泡接触时的具体条件,使矿物的分选粒度(与常规浮选法相比)增大到5至10倍,同时,这一分选技术大大提高了分选速度,从而使选矿基建投资和生产成本降低30～40%。在苏联,还采用泡沫分选法分选钾石盐、磷钙土、含金刚石矿石、金、锰、锡和其他矿石。马列诺夫斯基于1961年提出了泡沫分选
In recent years, the Soviet Union has developed a new method of beneficiation known as “foam sorting,” which has been applied industrially. This method is based on the choice of wettability of the mineral surface. Due to the specific conditions of the solid particles in contact with the bubbles, the sorting particle size of the mineral (compared with the conventional flotation method) is increased to 5 to 10 times, and at the same time, this sorting technique greatly improves the sorting speed, Infrastructure investment and production costs reduced by 30 ~ 40%. In the USSR, foam sorting is also used to sort potash salts, calcareous earths, diamond-bearing ores, gold, manganese, tin and other ores. Malinowski proposed a bubble sorting in 1961
