本装置设置在人形(山卡)矿山,用测定矿车矿石放射性强度的方法确定铀矿石的近似品位,并在给定品位限度下进行选矿,分出矿石车和废矿车。该装置是由11个盖格计数管组成的,这些计数管位于矿车周围的给定距离内,并具有计数线路和选矿线路。在预先规定时间(例如15秒)计数管接收到矿石的放射性,并由计数线路进行计数。接着由选矿线路表示出矿车是矿石还是废矿。用这种装置能够在给定的暂短时间内测定山整个矿车的放射性,并能把矿石车与废矿车分选出来。利用这种装置进行试验证明,铀矿石品位与放射性计数值密切相关。该装置的选矿性能是良好的。
The device is located in the humanoid (mountain card) mine, with the determination of radio ore ore radioactive intensity approach to determine the approximate grade of uranium ore, and in a given grade limit beneficiation, separation of ore car and scrap car. The unit consisted of 11 Geiger counting tubes, located within a given distance around the tub, with counting and dressing lines. The tubes receive the radioactivity of the ore at a predetermined time (eg, 15 seconds) and are counted by the counting circuit. Next, the ore dressing line is used to indicate whether the ore is an ore or a waste ore. With this device it is possible to determine the radioactivity of the entire tub in a given short period of time and to separate the ore car from the spent car. Experiments using this device demonstrate that uranium ore grades are closely related to radioactive counts. The dressing performance of the unit is good.
