| Abundant deposits of sulfate minerals, such as barite and celestite, are exploited for the preparation of metal salts. |
| Small amounts of fluorite, celestite, howlite have also been found at Cheverie. |
| Some chapters, such as the one on celestite and strontianite, are only two pages long, listing their seven uses. |
