Gravity separation is adopted for most of the antimony ore because of ite 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. Jigging separation is the main separation method for antimony oxide.

As a professional R & D jigger manufacturer, Gongyi Forui Machinery Factory has the perfect trial platform. Forui can do test for you here for your antimony ore beneficiation if your samples of about 20kg can be available.
