七十年代初,在我国大部分选矿试验室仍然用着五十年代苏式陈旧的设备,这种状况对我国选矿工艺赶超世界先进水平非常不利。在全国工作重点转移之后,为了改变这种落后状况,以适应四个现代化的步伐,地质部勘察技术研究院、地质部地质装备工业局及其所属的长春、武汉、贵阳、柳州探矿机械厂、西昌一○二厂、天津矿山仪器厂等单位设计试制了不少新的具有七十年代水平的选矿试验设备,为选矿试验设备的更新换代做了不少贡献。
In the early seventies, most of the ore dressing laboratories in our country still use the Soviet-style obsolete equipment of the 1950s. This situation is very unfavorable to our country's mineral processing technology to catch up with the advanced world level. In order to change this backwardness and to adapt to the pace of the four modernizations, the Geological Survey and Technology Research Institute, the Bureau of Geology and Equipment, and the Geotechnical Equipment Industry Bureau of the Ministry of Geology and the Changchun, Wuhan, Guiyang and Liuzhou Prospecting Machinery Factory, Xichang 102 plants, Tianjin Mining Instrument Factory and other units designed to trial a lot of new 70-year-level beneficiation test equipment, testing equipment for the beneficiation has made a lot of replacement.
