尼润波里矿区的锰矿选别流程包括:将破碎过的矿石筛分成+30公厘;30-15公厘;15-0公厘三级;沿长路(指洗选时间长一译者)洗选较粗粒节级的矿石,而细粒筛级的矿石则沿短路(指洗选时间短一译者)洗选;将矿石筛分成+10(8)公厘,10-1(8-3)公厘和1-0(3-0)公厘三级;如选别泥质矿石时,将各筛级的矿石跳汰;如选别砂质矿石时,则将组粒筛级的矿石跳汰;从洗矿机的矿泥中回收细粒矿石并加以精选。尼润波里锰矿公司选矿厂洗矿机的矿泥中含有金属矿物和非金属矿物的颗粒。此种矿泥的颗粒成份示於第一图(曲线1)。在全部技术操作工序中, The process of sorting and sorting manganese ore in the Nurunpur mining area includes the following steps: sieving crushed ore into +30 mm, 30-15 mm, and 15-0 mm; classifying the long path ) Of coarse ore grades, while fine grained ore grades are washed along a short circuit (meaning a short wash time); the ore is sifted to +10 (8) mm, 10-1 ( 8-3) mm and 1-0 (3-0) mm 3; if the selection of shaly ore, the various levels of ore jigging; such as sorting of sandy ore, then the group sieve Grade ore jig; reclaims the fine ore from the mine sludge in the ore washing machine and selects it carefully. Nimrod Pori manganese ore company ore dressing plant ore contains metal minerals and non-metallic mineral particles. The particle composition of such slime is shown in the first plot (curve 1).
