膨润土矿藏遍及五大洲,产量庞大,市场广阔,对许多工业部门有举足轻重的影响。但目前的消费量下降。1980年全世界约38个国家的一百多个公司所产膨润土已降至643万吨。当前世界上美、印、南非、澳等国生产天然钠膨润土,而大多数国家的膨润土则是钠交换嘭润土,另一些公司则将钙膨润土与酸作用制成酸活化膨润土,或者就直接销售一般加工过的钙膨润土。一生产综述北美洲北美洲在世界膨润土生产中占绝对优势,而美国更是独占鳌头,1980年的产量约占世界总产量的60%。
Bentonite deposits are found on five continents, yielding a vast and vast market that has decisive impact on many industrial sectors. However, the current consumption has dropped. In 1980, bentonite from more than 100 companies in 38 countries around the world had dropped to 6.43 million tons. The current world, the United States, India, South Africa, Australia and other countries produce natural sodium bentonite, and most countries are bentonite bentonite sodium exchange, while others will be made of calcium bentonite acid and acid activated bentonite, or directly Sales of general processing of calcium bentonite. A production review North America North America accounted for the absolute advantage in the world production of bentonite, while the United States is the champion, in 1980 the output of about 60% of the world’s total output.
