(一) 引言在毛主席关于“开发矿业”的指示指引下,随着地质科学研究工作的深入发展,单矿物分离任务也越来越大。近年来,我所供测同位素年龄所需的黑云母等单矿物分离任务较大,就现有的分离设备尚不能适应。为了较快地提取足够数量的纯黑云母等矿物样品,在党组织的直接领导下,参照有关单位的先进经验,购置部分零件,走自力更生的道路,实行了工人、干部和技术人员“三结合”,采取边试边改的方法经过两个多月的时间,突破了一些技术难关,终于试制成一台72-2型高压静电分离仪(图1)。
(1) Introduction Under the guidance of Chairman Mao’s instruction on “mining development”, with the deepening development of geological scientific research, the task of separation of single minerals is also getting bigger and bigger. In recent years, the single mineral separation tasks such as biotite that I need to test the isotope age are larger, and the existing separation equipment can not be adapted yet. In order to quickly extract a sufficient amount of pure biotite and other mineral samples, under the direct leadership of the party organizations, with reference to the advanced experience of the relevant units, the purchase of some parts, take the road of self-reliance, the implementation of the workers, cadres and technicians " After taking more than two months to break through some technical difficulties, it finally made a 72-2 type high-voltage electrostatic separator (Figure 1).
