河北铜矿选矿厂坚持“独立自主,自力更生”的方针,在北京矿冶研究院的密切协作下,勇于创新,大干快上,在两台3.5米~3充气机械搅拌式浮选机工业试验的基础上,试制成功14米~3充气机械搅拌式浮选机。浮选机(共12台24槽)从试制到安装,仅用了两个半月的时间。当时正是河北唐山、丰南一带发生强裂地震,波及矿区,给试制工作带来了一定的影响,然而担任浮选机研制任务的同志们以英雄的唐山灾区人民为榜样,在余震经常发生的情况下,克服种种困难,坚持大干。伟大袖领和导师毛主席逝世的噩耗传来,全体
Hebei Copper Concentrator adhere to the “independent, self-reliance” approach, in close cooperation with Beijing Institute of Mining and Metallurgy, the courage to innovate, big fast, in the two 3.5 m ~ 3 pneumatic mixing flotation machine industrial test On the basis of successful trial of 14 m ~ 3 aerated mechanical stirring flotation machine. Flotation machine (a total of 12 24 slots) from trial to installation, only took two and a half months time. At that time, it was a strong rift earthquake in Tangshan and Fengnan in Hebei Province which affected the mining area and brought a certain impact on the trial production. However, comrades working on the development of flotation machine took the example of the heroic people in Tangshan disaster area and frequent aftershocks occurred In the circumstances, overcome all kinds of difficulties and persist in doing a good job. The bad news came when the great sleeves and mentor Chairman Mao died, all
