Coalinga Chrysotile under the Microscope

Acid leaching studies of chrysotile asbestos from mines in the Coalinga region of California and from Quebec and British Columbia.

The dissolution of magnesium (Mg) and silicon (Si) from various samples of chrysotile asbestos was measured in N HCl at 25 degrees C. Nine samples were used, five from Canada and four from the Coalinga deposit in California. With milled samples from Quebec, the fraction of Mg dissolving was linearly related to the square root of the leaching time until at least 65% had dissolved. With a hand-pi...
