本钢南芬选厂在北京矿冶研究院设备室的大力协助下,在取得螺旋溜槽单机回收尾矿试验成果的基础上,今年安装了22台,于1978年4月至6月进行了连续性的扩大工业试验。试验采用的流程是:选厂尾矿经浓缩,沉砂进入粗选和精选螺旋溜槽,精选溜槽得到的中矿入中矿再选溜槽进行选别,其精矿与精选溜槽的精矿合併为螺旋溜槽之精矿;其中矿再返回至
With the help of the equipment room of Beijing Institute of Mining and Metallurgy, Benxi Iron & Steel Co., Ltd. installed 22 sets of this year’s tailings test results from the stand-alone tailings recovery of the spiral chute and carried out continuous operation from April to June 1978 Sexual expansion of industrial tests. The process used in the test is as follows: concentrating tailings by concentrating, grit entry into roughing and selection of spiral chutes, selection of middle mines from selected chutes into secondary mines for re-selection of chutes, selection of concentrate and fine chute Mine merged into a spiral chute concentrate; which mine and then returned to
