Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb2S3. This soft grey material crystallizes in an orthorhombic space group.[6] It is the most important source for the metalloid antimony.[7] The name is derived from the Greek στίβιstibi through the Latin stibium as the former name for the mineral and the element antimony.[3][4]
