1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as 'regulus', melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of …

Sometimes, even if it can not directly select qualified antimony concentrate, it is often selected as a pre-selection operation for antimony flotation operations. Especially when flotation has many difficulties in processing antimony oxide ore at this stage, gravity separation is the main beneficiation method for antimony oxide ore.

Especially for sulfide antimony ores, the most common beneficiation method is flotation. Therefore, antimony ore consisting of stibnite mineral obtained from Tokat-Turkey region was used in this study. Due to the low antimony (5.06%Sb) and the high Arsenic (1.38%As) content, it is an important requirement to increase the Sb content of this ore ...
