一、前言遵照毛主席关于“打破洋框框,走自己工业发展道路”和“尽量采用先进技术”的教导,自1970年以来,对应用高频原理等新技术分选矿物(以下简称高频选矿)做了一些工作。1970年上半年江西有色冶金研究所研究应用高频选矿分选单体钨、铜获得了初步成效,但还存在电路互相干扰等问题。为了深入探讨和解决存在问题,结合选矿的特点,学习了有关兄弟厂矿和科研单位的经
I. Preface In accordance with Chairman Mao’s teachings on “breaking the framework of the world and taking the path of industrial development” and “adopting advanced technologies as far as possible”, since 1970, the application of high-frequency principles and other new technologies for the separation of minerals (hereinafter referred to as high-frequency beneficiation Did some work. In the first half of 1970, Jiangxi Institute of Nonferrous Metallurgy researched and applied the high-frequency beneficiation and sorting monomer tungsten and copper to obtain preliminary results, but there were also problems such as circuit interference with each other. In order to further explore and solve the existing problems, combined with the characteristics of beneficiation, learning about the brothers and mines and scientific research units of the
