摘要
论述中国硫资源的结构特点,生产、利用现状,以及潜在的硫资源。指出硫铁矿仍将是中国今后主要的工业原料;伴生硫铁矿的开采要综合评价其有用组分的利用;中国的煤炭资源丰富,其平均含硫量为1.31％,是较大的潜在硫资源;提高冶炼烟气中SO_2的回收利用率,加强从天然气、石油中回收硫,利用天然石膏、磷石膏制酸,都是充分利用硫资源的有效措施。建议根据国情保持普钙产量的比例。
Structure, Character, production and usage of sulfur resource in China,as well as latent sulfur resource is described. Pvrite is main sulfur resource. For the associated pyrite.the use of its useful components needs to be evaluated. Coal .which is rich in China with average sulfur content of 1. 3% ,is a latent large resource. To enhance SO2 recovery from flue gas in metal industry, as well as sulfur recovery from natual gas and petroleum , to use natural gypsum and phosphoretted gypsum for producing acid, these measurement are effective for the full use of sulfur resource.
It is suggested that the output of common calcium fertilizer should be kept at a definite proportion based on domestic condition of sulfur deficiency in soil.
