| 摘要 |
The invention relates to a flotation machine which at least contains a flotation cell having a means for feeding slurry in the flotation cell, a means for feeding air into the slurry and producing froth, a means for removing froth from the flotation cell and a means for removing tailings from the flotation cell. According to the invention the flotation cell ( 1,21 ) is provided with at least one rotating froth removal device ( 8,26 ) immersed at least partly in the froth ( 9,27 ) and so shaped that one end of the froth removal device ( 8,26 ) is extendible over the launder ( 12 ) attached to the flotation cell ( 1 ) in order to recover the froth ( 9,27 ) from the flotation cell ( 1,21 ) using the centrifugal force generated by the froth removal device ( 8,26 ). |
