Stibnite - an overview ScienceDirect Topics

Stibnite floats well in neutral and weak acid pH, while in an alkaline pH (i.e. >8), it is reduced. Utilizing this phenomenon, gold-bearing sulfides are floated with xanthate and alcohol frother in alkaline medium (pH>9.3) followed by stibnite flotation at about pH 6.0, after activation with lead nitrate.

Stibnite - an overview ScienceDirect Topics

Antimony (Sb; CASRN 7440-36-0) is a semimetal element with chemical properties similar to lead, arsenic, and bismuth. In nature, it is found associated with sulfur as stibnite. Antimony is used in white metal, a group of alloys having relatively low melting points. White metal usually contains tin, lead, or antimony as the chief component.

Mar 01, 2014  This study aimed to introduce a comprehensive process for separating and recovering antimony from a complex stibnite concentrate. Antimony is first leached through a chlorination–oxidation procedure to obtain SbCl 3 solution. Antimony is then recovered in the forms of cubic crystal Sb 2 O 3 (99.9%), high-purity cathode antimony (99.98%), crude cathode antimony (99.7%), high-purity SbOCl

Antimony - Arkansas

However, stibnite and antimonial lead ores are the main sources of the metal. Stibnite (Sb2S3) and stibiconite (Sb3+Sb25+O6(OH)) were the only minerals mined in Arkansas for this metal. Stibnite is steel-gray, has a relatively high specific gravity (4.6), a metallic luster, and often forms slender prismatic crystals that may have a curved habit.
