19 ABSTRACT OF THE DISCLOSURE Disclosed is a process for manufacturing of pellets of chrysotile asbestos fibers, wherein asbestos fibers containing from 5 to 20% by weight of water are pelletized to form wet pellets that are subsequently dried until their residual water content reaches 0 to 1% by weight. Then, an aqueous solution or suspension of a substance compatible with the intended use of the pellets is sprayed onto the same to form a selective protective coating that eliminates release of asbestos dust and air- borne particles. The obtained pellets have excellent mechanical properties that make them easy to handle, thereby allowing safe and easy transportation of chrysotileasbestos in bulk.
