Abstract
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 airborne particles. The obtained pellets have excellent mechanical properties that make them easy to handle, thereby allowing safe and easy transportation of chrysotile asbestos in bulk.
