Asbestos Mining and Production of Chrysotile-Containing Products Is Going Full Bore in Brazil
Some think that asbestos use is is over or dwindling all across the world. Not true.
For example, this new press release from Eternit S.A. reports on the company's better than expected quarter of asbestos mining, and manufacturing of various asbestos-cement products.
"SAO PAULO, Aug. 9, 2011 /PRNewswire/ -- Eternit S.A. (BM&FBOVESPA: ETER3; OTC: ETNTY), a company with 71 years of activity and the market leader in roof coverings, panels and cement slabs, today announces its results for the 2nd quarter 2011 (2Q11).
Although 2Q11 is seasonally the weakest period of the year, Eternit operated at full capacity in its chrysotile mining business, above 90% in fiber cement production and in excess of 80% in concrete tiles.
At this page, Eternit SA's website also provides this information on asbestos fiber production:
"Chrysotile asbestos and amphibolic asbestos
There are two main groups of asbestos, chrysotile and amphibolic. Amphibolic asbestos has hard fibres which are straight and pointed, as well as having a high concentration of iron in their composition. Chrysotile asbestos has curved fibres which are silky and have a high concentration of magnesium in their composition. The characteristics of these fibres is one of bio-persistence, which signifies the amount of time that they remain in the lungs before being eliminated. Chrysotile fibre remains a maximum of two and a half days in the lungs, whereas amphibolic fibre remains more than a year.

The history of the Cana Brava mine - controlled by SAMA S.A. - Minerações Associadasis confounded with the development process of the inland Brazil in the second half of the 20th Century, particularly in the Central-Western region. The first pioneers who arrived at the place, in 1962, searched for clues of strange"hairy stones" in a region occupied by a few families living along the rivers.--
