Antimony Mineral Processing

Solution Introduction

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.

Solution Appliion

Xinhai’s gravity separation-flotation Process is applied to all kinds of antimony ore.

Solution Description

Xinhais gravity separation-flotation Process.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 classifiion 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 floatation the tailings from the preview gravity separation will be grinded separated stirred and floated. And the floatation will apply the Process of andldquoone roughing three cleanings and two scavenging and rd.Then high grade antimony fine powder will be produced. The tailings from the floatation will be reelected by shaking table to recycle the fine antimony particles which we can get high grade antimony concentrate and tailings.

Solution Case

In one of Xinhais project antimony content is 3.19 among which the share of antimony sulfide is about 95.30 and a small amount of antimony is existed in valentinite or antimonite about 4.70. Carbon content of the ore is 6.43 in which the inorganic carbon have up to 5.46 and is antimony sulfide with high-carbon and very complex for dressing. After multi scheme of test Xinhai finally decided to use gravity separation-flotation Process to recycle the antimony ore and in the test the grade of antimony is 58.71 the recovery rate of mixed antimony concentrate Is 93.75. Genius achieved the maximum intensity of the recovery of the antimony ore which reduced the environmental pollution caused by tailings and also gained excellent economic benefit.
