Proportion of antimony ore is far greater than proportion of gangue, so it will be separated by using the method gravity separation. This method has many features, high efficiency, energy saving, and environment protection, which can make the low-grade ore enrichment advance. After gravity separation, the antimony will be purified by floatation. So the processing method of Xinhai is gravity separation-flotation process.
Xinhai's gravity separation-flotation process is applied to all kinds of antimony ore.
The ore after hand sorting will go through coarse crushing and fine crushing, during which the size of mineral should be under 30mm, and screening classification have three size fractions, 8-30mm, 2-8mm, 0-2mm. then the three kind of minerals will go respectively into Xinhai AM30 Jig, Xinhai LTA1010/2 Jig, and Xinhai Sawtooth Wave Jig to gravity separation. The mixted concentrate from the last stage will be go into the gravity concentrate district. Then after the process of gravity, there will be a process of flotation, the tailings from the preview gravity separation will be grinded, separated, stirred, and separated. And the flotation will apply the process of one roughing, three cleanings, and two scavenging. Then high grade antimony fine powder will be produced. The tailings from the flotation will be reelected by shaking table to recycle the fine antimony particles, which we can get high grade antimony concentrate and tailings.
