Antimony Ore Beneficiation Washing Plant
 

There are three kinds of antimony ores according to the beneficiation technology. And they are single antimony sulfide, stibnite and antimony sulfide-oxide mixture. There is some other antimony ore mixed in stibnite ore together with some lead, tungsten, mercury minerals. The main separation way for these three antimony ore is hand selection, gravity separation and floatation separation. For some complex antimony ore, hand selection, gravity separation and floatation separation can be used together, and here Forui shares some about antimony beneficiation flow sheet.

The antimony ore processing line is to gain high grade antimony concentrate, and the flow sheet can be designed according to antimony ore structure and inlay situation. And here is some antimony beneficiation to share with you.

Hand selection to get antimony blocks according to the different colors, gloss, and shape of antimony and other materials. And it works by human power and asks for high requirement about the coarse inlay. This method can help to get high grade antimony concentrate directly for smelting.

Gravity separation can be used for most of antimony ore with its bigger density than other material and coarse inlay. No matter antimony oxide or antimony sulfide or mixture of antimony oxide and sulfide, gravity separation can do a great job to get high grade antimony concentrate, especially for antimony oxide which floatation separation can not work.

Floatation separation is the main beneficiation method for antimony ore. Antimony sulfide is kind of floatable ore and floatation separation can help get good efficiency. Lead salt can be used as activator, xanthate or shate oil as collectors, and terpenic oil as foaming agent. For antimony oxide, gravity separation can be the most common way to work because it is difficult to float.

According to the share above, the antimony processing line can be designed easily. For single antimony sulfide ore, hand selection-gravity separation-floatation separation can be used to get lumpy concentrate granule antimony concentrate and fine antimony concentrate while for antimony sulfide, gravity separation can be used to get high grade antimony concentrate. Combination of floatation separation and gravity separation can be used in beneficiation of antimony oxide-sulfide.

Forui is a professional manufacturer of kinds of mining equipments, and free test can be supplied if samples can be available. Flow sheet with plant details can be designed according to the sample test.
