Study on the Effect and Mechanism of Calcination of Asbestos Tailings Mixed with Ammonium Sulfate The research involves the calcination of Sichuanshimian asbestos tailings with ammonium sulfate in order to extract magnesium.
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....Chat Now
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....Chat Now

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)....Chat Now
