世界滑石探明储量为3.77亿t,遍及40多个国家和地区,但主要集中在美国、巴西、前苏联、中国、印度、日本、韩国等国。前苏联滑石储量占各国之首,其次是中国,美国第三。 近年世界滑石年产量不足900万t(1992年为896.1万t),其中产量最大的是中、日、美三国,年产量均在百万吨以上。中国年产量23O万t,日本129.5万t,美国103.7万t,三国的产量占世界滑石产量的52％。
The proven reserves of talc in the world are 377 million tons, covering more than 40 countries and regions, but mainly in the United States, Brazil, the former Soviet Union, China, India, Japan, South Korea and other countries. In the former Soviet Union, talc reserves accounted for the first in all countries, followed by China and the United States. In recent years, the annual output of talc in the world has been less than 9 million tons (89.61 million tons in 1992), of which the largest output is China, Japan, and the United States. The annual output is more than one million tons. China’s annual output is 230 million tons, Japan is 1.295 million tons, and the United States is 1.037 million tons. The output of the three countries accounts for 52% of the world’s talc production.
