Several problems peculiar to chrysotile asbestos ore bodies affect the practice of draw control. Heterogeneous fragmentation, cavities, side pressures and the interaction of stresses in the caved ore affect the migration of ore under draw. Fibre is normally not developed uniformly throughout the ore bodies, values vary from place to place but there is usually a general decrease upwards and the ...

Because asbestos mining relied on "dry milling and air flotation, the methods used to control silica dust in gold mines could not be applied to asbestos mills" (p. 21). Therefore, asbestos workers remained at risk. Later in the 1960s, when South African medical practitioners recognized mesothelioma, an incurable disease that can arise from even minimal exposure to asbestos fiber, the industry ...
· A littleknown kind of asbestos, tremolite, laced the ore used in the spray. And while Grace knew this, for years it kept that knowledge largely hidden from workers who applied the fireproofing ...
Vermiculite ore from Libby contains lethal tremolite asbestos. Grace's processing facilities refine vermiculite ore, but tremolite remains in abundant quantities after the process. Grace commissioned animal studies in 1977 that proved that asbestos from the Libby mine caused cancer, but did not release the details to the work force or leaders of their union. In 1999, after the coverup ...
· • Wet methods must be applied during asbestos removal and packaging.

The Asbestos Institute does not mention the fact that crocidolite and amosite are also present in the mine ore, and claims that tremolite is removed through various mining and milling processes [De, 1961; Browne, 2000]. This is simply untrue. In fact, other McGill researchers have shown that a substantial quantity of the mined tremolite ends up in the lungs of textile workers [Gibbs, 1972 ...
Answer (1 of 5): I would not recommend doing this. Painted popcorn ceiling texture often pulls off in sheets when it is removed. If you are using drywall mud to "bury" a popcorn ceiling, you will be adding a lot of weight to the ceiling. The only thing it will adhering to is the popcorn texture....
