Asbestos is a naturally occurring silicate mineral excavated mainly in Asian and Middle Eastern countries. Despite its toxic effect on humans (asbestosis, lung cancer, mesothelioma, and other malignant tumor and pleural diseases) and environment pollution problems (airborne diseases and metal enrichment in water and soil), its production is still in progress.

Asbestos is a carcinogen, and medical reports indicate a single fiber can cause lung cancer. There is little health risk if the material is fully intact and is properly maintained; but it can quickly turn dangerous if any of the fibers become friable and airborne, and are inhaled. Asbestos has been used in a wide variety of products and materials.

BGMEA University of Fashion & Technology Page 10 The chemical feature common to all asbestos is that they are hydrated silicates The degree of hydration varies from approximately one per cent in some types to as much as approximately 14 per cent in most kinds of chiysotile It generally accepted that asbestos is a metamorphic product derived ...

The hand cobbing asbestos mining operation involves releasing fiber from the asbestos ore rock by means of manually (by hand) hammering away the rock from the ends of fibers. This type of fiber is not processed through the standard crushing units during the milling operation of the shorter filers. See Figure 1.4 at left.

Asbestos is known to cause asbestosis and various forms of cancer. Asbestosis is a chronic disease of the lungs which makes breathing progressively more difficult, and can lead to death. Cancer can result from breathing asbestos fibers and lung cancer is the most frequent. Mesothelioma, an incurable cancer of the chest and abdominal membranes ...

Use of asbestos declined rapidly, with many countries banning the substance, and extensive efforts made to remove asbestos from buildings.
