Water Filtration for Asbestos Fiber Removal

----ABSTRACT This report was prepared so that concepts of water filtration for asbestos fiber removal could be presented in a manner that would explain results reported by other investigators, to provide information for designers of water filtration plants, and to give guidelines for the successful operation of filtration plants that are removing asbestos fibers from drinking water.

2013-1-2 · Atmospheric CO2 is sequestered within ultramafic mine tailings via carbonation of Mg-bearing minerals. The rate of carbon sequestration at some mine sites appears to be limited by the rate of CO2 supply. If carbonation of bulk tailings were accelerated, large mines may have the capacity to sequester millions of tonnes of CO2 annually, offsetting mine emissions....

How mine tailings could help in the fight against

The research could even help remediate the three million tonnes of deadly asbestos tailings in the gorges of Wittenoom. Mr Southam said it was possible the bacteria could break down Wittenoom's asbestos piles, but it was unlikely to carry the same environmental benefit as other deposits.

Asbestos was considered by previous IARC Working Groups in 1972, 1976, and 1987 (IARC, 1973, 1977, 1987a). Since that time, new data have become available, these have been incorporated in the Monograph, and have been taken into consideration in the present evaluation....

Pot culture studies with chrysotile asbestos mine tailings from Barraba, New South Wales, Australia, showed the residues to be deficient in nitrogen, phosphorus, potassium and calcium. Barley grew normally only when superphosphate and gypsum were applied at rates equivalent to 5 and 16 t

Tailings are the waste materials remaining after physical or chemical beneficiation operations remove the valuable constituents from the ore. Tailings generally leave the mill as a slurry, consisting of 50 to 70 percent (by weight) liquid mill effluent and 30 to 50 percent solids (clay, silt, and sand-sized particles)....
