我矿将选所使用的φ3000×3000毫米的搅拌槽,系苏联供应设备(仅木制槽体是国内按苏联设计制作的),开工以后一直不能使用,原来在驻厂苏联专家指导下,更换过三次电机(原设计为4.5瓩,以后更换为7瓩、10瓩和20瓩),矿砂仍然在槽内沉积,以后又将槽子容积缩小槽底填混凝土500毫米仍然不能使用,几年以来,一直由7A浮选机二台代替一台搅拌槽使用,因而缩短浮选时间,降低了铜的金属回收率。在党的自力更生、奋发图强的方针指引下,经过技术人员与工人共同研究以及选矿研究院同志的帮助,从去年
I mine will choose the use of φ3000 × 3000 mm stirring tank, the Soviet Union supplies equipment (only wooden tanks are designed by the Soviet Union), started after the can not be used, the original plant in the Soviet Union under the guidance of the Soviet Union, the replacement Three times the motor (4.5 瓩 in original design, later replaced by 7 瓩, 10 瓩 and 20 瓩), the ore is still deposited in the tank, and later the tank volume is reduced. The concrete at the bottom of the tank is still unable to be used for 500 mm. 7A flotation machine has been replaced by a mixing tank to use, thus shortening the flotation time and reduce the metal recovery of copper. Under the guideline of the party’s self-reliance and hard work, through the joint research of technicians and workers as well as the help of the dressing institute comrades,
