摘要
介绍了国内外浮选柱的发展概况和部分浮选柱的结构。我国浮选柱与国外浮选柱相比,性能不相上下,但因我国电力不足,无法保证矿山供电,浮选柱经常停车,频繁放矿,金属矿物大量流失,选矿厂宁可再度采用浮选机。文中指出了我国浮选柱复苏的条件。
The general development situation of flotation column in China and other countries, and constructions of flotation columns are described. It is held that the performances of China-made flotation columns are compared to those manufactured abroad. However shortage of electricity has restricted their wide application in China. Since the power supply to mineral processing plants are not guaranteed, flotation columns have been shut down frequently, as a result the pulp in the column must be draw off and large quantities of minerals washed away. In view of this, mineral dressing plants would rather use flotation machines than columns. Finally, necessary conditions are proposed to rehabilitate the wide introduction of flotation columns.
