火山硫矿床可能是分布最广泛的自然硫矿床,这类矿床在世界大部分火山区都有发现。它主要分布在太平洋沿岸国家和地区,如中美、南美、日本、菲律宾、中国台湾省、新西兰和苏联等。目前火山硫产量约占世界硫产量的1.4％,主要为自销。火山硫的采矿方法有巷道法、房柱法、分层充填法空场法和露采法。用熔化、蒸馏、烧结、浮选溶剂 Volcanic sulfur deposits are probably the most widely distributed natural sulfur deposits that have been found in most volcanic areas of the world. It is mainly distributed in Pacific Rim countries and regions such as China and the United States, South America, Japan, the Philippines, Taiwan Province of China, New Zealand and the Soviet Union. Volcano sulfur production currently accounts for about 1.4% of the world’s sulfur production, mainly for self-marketing. Volcanic sulfur mining methods are roadway method, the Housing Method, stratified filling method of open field method and open mining method. With melting, distillation, sintering, flotation solvent
