选矿过程的检测或自动化,一般开始是以过程的各个控制量为对象,逐渐过渡到全过程的自动控制。八茎选旷厂精矿脱水过程的自动控制,于69年装设,稳定地生产至今。预定在72年实现集中控制。概要情况介绍如下。一、铁精矿的脱水选矿厂生产的铁精矿,是以磁选的方法,由铜浮选尾矿中回收的。精矿中—325网目占80％(铁精矿粒度分布如表1),含铁63％。
Dressing process testing or automation, the general beginning is based on the process control of each volume as the object, the gradual transition to the entire process of automatic control. Eight stem electoral plant concentrate dehydration process of automatic control, installed in 69, stable production so far. Scheduled to achieve centralized control in 72 years. The outline is as follows. First, the iron concentrate dehydration Concentrator concentrate produced by magnetic separation method, recovered from the copper flotation tailings. Concentrate -325 mesh accounts for 80% (iron ore particle size distribution in Table 1), iron 63%.
