Stibnite (Sb2S3), the principal natural source of Sb in the environment, is linked to the parent weathering material of sinarmonitis (cubic Sb2 O 3 ), stibiconite (Sb 3 O 6 OH), and valentinitis (orthorhombic Sb 2 O 3) ( Hu, Guo, He, & Li, 2016 ). It has been calculated that volcanic activity is responsible for 3%–5% of worldwide Sb emissions ...

Sb2S3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Sb2S3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded to five S2- atoms to form SbS5 square pyramids that share corners with two equivalent SbS6 …

Stibnite, đôi khi gọi là antimonite, là một khoáng chất sulphit với công thức Sb 2 S 3.Vật liệu màu xám nhạt kết tinh trong một nhóm không gian ảo. Đây là nguồn quan trọng nhất cho antimony kim loại. Tên gọi từ tiếng Hy Lạp στίβι stibi thông qua tiếng Latin stibium là tên cũ của khoáng chất và antymon nguyên tố.

Antimony–this metalloid element occurs in nature as a sulfide ore (stibnite – Sb2S3). Once purified, antimony was called regulus in medieval times, or earlier in history, flowers of antimony . Both purified antimony and stibnite are employed at specific phases in the archetypal synthesis.

The kinetics of oxidative dissolution of natural stibnite (Sb2 S 3) under environmentally relevant conditions is investigated. The effects of hydrogen ion activity (pH 1.08–10.63), dissolved oxygen saturation (p (O2) from 0 to 80% of atmospheric pressure), and temperature (25–48 °C) on the reaction rate were studied using a mixed flow reactor.

La stibnite Sb2S3 è un minerale, un solfuro di antimonio. Sono suoi sinonimi antimonite e stibina. Il nome stibnite deriva da stibio, voce desueta per antimonio, e (antimo)nite. Il nome stibina deriva dal greco στίβι = nero-antimonio, conosciuto già nell'antichità. Il nome antimonite deriva forse dall'arabo 'utmud.

Antimony (Sb) is obtained by heating pulverized stibnite (Sb2S3) with scrap iron and drawing off the molter antimony from the bottom of the reaction vessel. Suppose that 6 kg of stibnite and 2.5 kg of iron turnings are heated together to produce 2 kg of Sb metal. MW of Sb2S3, Fe, and Sb are 339.7, 55.85, and 121.8 respectively.
