十多年来,浮选槽一直是引人注意的中心问题。在七十年代,2～3米~3的浮选槽被8米~3的槽所取代,当前浮选槽的容积已增大至 42米~3。芬兰Outokumpu Oy公司认为在大型选矿厂中100米~3的浮选槽是最经济的。对于大型浮选槽,人工不再能控制矿浆液面和泡沫深度了,必须实现自动化控制。Agitair浮选机安装了直径小,转速低的新型转子。Dorr—Ol(?)ver公司引用了新的浮选机设计 For more than a decade, the flotation cell has always been an attractive central issue. In the seventies, 2 ~ 3 m ~ 3 flotation cells were replaced by 8 m ~ 3 troughs. The current capacity of the flotation cells has been increased to 42 m ~ 3. Outokumpu Oy, Finland, considers the most economical of 100 to 3 flotation cells in a large beneficiation plant. For large flotation cells, man-made is no longer able to control the slurry level and foam depth, and must be automated. The Agitair flotation machine is equipped with a new rotor with a small diameter and low speed. Dorr-Ol (?) Ver cites the new flotation machine design
