Processing of California bastnasite ore

In 1949, a large radioactive ore body was discovered in the Mountain Pass District of San Bernadino County, Cal­ ifornia (IT). Although the chemical analysis of the ore indicated that it contained less than 0.1 per cent thorium, the analysis indicated that the ore contained an average of 5 to 15 per cent bastnasite. Shortly after the deposit
