为了提高某选厂的处理能力,以追求选矿的规模效益,在对磨矿系统和浮选系统的设备未做任何改进的情况下,将选矿能力由600t/d提高到850t/d,但磨矿细度和浮选指标明显下降,其原因是浮选时间缩短,而非细度下降。在几乎未投入资金的情况下,仅对浮选流程进行了改进,即相对延长了浮选时间,使浮选指标较改进前明显提高,达到了提高选厂处理能力的目的。
In order to improve the processing power of a selected plant, in pursuit of the economies of scale of beneficiation, the ore dressing capacity was increased from 600 t / d to 850 t / d without any improvement to the equipment of grinding system and flotation system, but the mill Mine fineness and flotation index decreased significantly, the reason is the flotation time is shortened, not the fineness of decline. In the case of almost no investment, only the flotation process has been improved, that is, the relative extension of the flotation time, the flotation index improved significantly before the improvement, to achieve the purpose of improving the processing power plant.
