FORUI STIBNITE ANTIMONY ORE BENEFICIATION PLANT-ANTIMONY ORE WASHING EQUIPMENT

The single antimony sulfide ore is stibnite, and its main separation methods cover hand-selection, gravity separation, floatation separation, and here the jigging gravity separation will be introduced.
 
Gravity separation is adopted for most of the antimony ore because of its big density and coarse granularity size to make the gravity separation good enrichment efficiency. The density of the stibnite is 4.6 while that of the gangue is 2.6, so stibnite is very easy to separate by gravity separation. Jigger is one of the gravity separation machines widely used for stibnite separation.

Jigging gravity separation separates based on the density difference of the concentrate & the gangue with its great enrichment efficiency & large handling capacity. Jigger can deal with a large range of size and is friendly to environment with high cost performance, so it is the ideal separator for stibnite ore. For some antimony hard to separate, jigging gravity separation can only work as the pre-separation of floatation separation, especially for the antimony oxide. and jigging separation is the main separation method for antimony oxide.
 
After crushing and vibrating screen, the antimony ore can be divided into three size ranges of 8-30mm, 2-8mm, and 0-2mm. These three ranges will be fed into jiggers of AM30, LTA1010/2 and JT1070/2 correspondingly for jigging gravity separation. There are some fine antimony granules in the tailings from the jigger. Milling-classifying-agitation-floatation separation can be usually adopted after jigging gravity separation in order to improve the recovery. Shaking table can be involved to get the fine antimony oxide granules in tailing from floatation separation. So flow sheet of crushing-screening-jigging gravity separation-milling-classifying-agitation-floatation separation-shaking table gravity separation is usually used for antimony beneficiation.
 
For some coarse inlay antimony ore, hand selection can be used to get the lumpy rich antimony blocks before crushing and jigging gravity separation.
 
Here Forui has kinds of jiggers and assistant machines for a whole antimony processing line. Also, a free test can be done for you if samples can be available, and detailed flow sheet with plants model can be designed according to the test.
