在金刚石选矿过程中,有两个重要问题:一是如何简化工艺流程;二是如何实现选择性破碎,降低金刚石晶体的机械破碎率。从而提高金刚石的回收率,降低基建投资,降低生产成本。过去的几年中,我们曾和一些单位协作,共同进行了砂矿的“宽级别跳汰”试验及“重介质选矿”试验,并对金刚石原生矿的“超声波碎矿”、“液电碎矿”、“自磨磨矿”等多种方法作了初步调查及探讨性的试验。1971年在领导的支持下,经过工人、技术人员的充分讨论,认为“自磨磨矿”在
In the process of diamond dressing, there are two important issues: First, how to simplify the process; Second, how to achieve selective crushing, reducing the mechanical crushing rate of diamond crystals. Thus increasing the diamond recovery rate, reducing capital investment and reducing production costs. In the past few years, we worked with some units to jointly carry out the “wide-level jig” test and the “heavy medium beneficiation” test for placer ore. We also conducted experiments on the “ultrasonic crushing” of diamond primary ore, Mine “,” self-grinding mill “and other methods made a preliminary survey and exploratory test. In 1971 with the support of the leadership, after full discussion of the workers and technicians, it was considered that ”self-grinding"
