北美的叶腊石工业主要集中在美国的北卡罗来纳州,加利福尼亚州和加拿大的纽芬兰。近年来,尽管销售市场有的上升,有的下降,但产量保持稳定。在美国,叶腊石主要用在陶瓷方面。美国1984年叶腊石产量大约为85,000短吨,加拿大为30,000吨。美国七十年代叶腊石的产量为120,000短吨,由于耐火材料市场衰退,导致产量下降。
The pyrophyllite industry in North America is mainly concentrated in North Carolina, California, and Newfoundland, Canada. In recent years, although some sales markets have risen and some have fallen, production has remained stable. In the United States, pyrophyllite is mainly used in ceramics. In the United States, the production of pyrophyllite was approximately 85,000 short tons in 1984 and 30,000 tons in Canada. The production of pyrophyllite in the United States in the 1970s was 120,000 short tons, which resulted in a decline in production due to the decline of the refractory market.
