在现行锰选厂中,高质量精矿多半是在风力脉动跳汰机中经跳汰选矿生产的。在实验室、半工业和工业条件下进行的试验研究,查明了对跳汰选矿过程有不利影响的一系列因素,这些因素通常会降低重选分离的效果。其中主要有:1)由于在每道工序中无控制水平水流的设备,因此,水流的高水平速度沿跳汰机长度方向增加;2) In the current manganese concentrator, high-quality concentrates are mostly produced by jigging in wind-pulsating jiggers. Experimental studies carried out in laboratory, semi-industrial and industrial conditions identified a number of factors that negatively affect the process of beneficiation of the jig which often reduce the effectiveness of re-separation. The main ones are: 1) The high horizontal velocity of the water flow increases along the length of the jig, due to the lack of equipment for controlling the horizontal flow in each operation; 2)
