硫是化学工业的基本原料,用量大,使用面广.硫的提取和利用主要取决于资源状况、技术条件和经济效益.一个国家的工业硫源结构是随着硫资源特点、科学技术进步和工农业生产的发展而变化的.世界上大量使用硫始于十八世纪初期,当时主要开采自然硫矿床,意大利西西里岛盛产自然硫,其产品一度控制了世界硫市场;从十九世纪五十年代起,自然硫产量供不应求,人们转向开发分布广泛的硫铁矿床,西班牙和葡萄牙的产量最大.在一段时期内,黄铁矿成为世界工业硫的主要来源.1894年开始用热水溶融法开发沉积型自然硫即弗拉斯硫,因其具
Sulfur is a basic raw material for the chemical industry. It has a large amount and a wide range of applications. The extraction and utilization of sulfur depends mainly on resource conditions, technical conditions, and economic benefits. The sulfur source structure of a country is related to sulfur resource characteristics, scientific and technological progress, and The development of industrial and agricultural production has changed. The world’s massive use of sulfur began in the early 18th century when natural sulphur deposits were mainly mined. Sicily, Italy, was rich in natural sulphur, and its products once controlled the world’s sulphur market; from the fifteenth century fifty. Since the beginning of the decade, natural sulphur production has been in short supply, and people have turned to the development of a wide range of pyrite deposits. Spain and Portugal have the largest production. In a period of time, pyrite has become the main source of industrial sulphur in the world. In 1894, it began to use hot water The development of sedimentary natural sulfur, ie fulas sulfur, is
