摘要: The bluish white, lustrous, very brittle metal (atom. no. 51, atom. wt. 121.75, specific gravity 6.69, melting pt. 631 °C) is found in nature more than 100 minerals. However, only about one dozen ores are commercially important, such as Sb oxides and sulfides, complex Cu—, Pb—, Hg—Sb the most important of which stibnite (Sb2S3). It also occurs with sphalerite, pyrite, galena minor amounts Hg deposits. In nature, it primarily III oxidation state.
