三度一准历来是浮选操作中极其重视的条件,而其中矿浆的粒度和浓度对金属的回收率有着直接的影响,如何搞好测定,国内外都作了大量工作.为了适应生产现场的迫切需要我们研制了矿浆浓细度的自动检测仪.在实验室成功的基础上,于80年在云锡大屯选厂进行在线试用,81年又在大姚铜矿选厂安装一了台,使用效果都良好. The third level has always been an extremely important condition in the flotation operation, and the size and concentration of the slurry have a direct impact on the recovery of the metal. How to do a good job of measurement, both at home and abroad have done a lot of work. In order to adapt to the production site There is an urgent need for us to develop an automatic detector for the consistency of the slurry.On the basis of the success of the laboratory, we conducted an online trial in the election of the plant in Yunxi Datong in 1980 and installed a station in Dayao Copper Mine in 2001 , The use of good results.
