Barley grew normally only when superphosphate and gypsum were applied at rates equivalent to 5 and 15 t ha1, respectively, together with normal rates of nitrogen and potassium.
Prepartion of FlakeLike Basic Magnesium Translate this pageThe flakelike basic magnesium carbonate was prepared from the ammonium sulfate leaching liquid of asbestos tailings. Calcium Phosphat Economical Poten 查看完整102 MAGNESIUM METAL1 minerals.usgs.govA company in Quebec, Canada, produced a limited amount of magnesium from serpentine contained in asbestos tailings at its 200tonperyear pilot plant and was planning to construct a 50,000tonperyear plant. Another company was testing its process for producing magnesium from serpentinebearing asbestos tailings in the same region of Quebec.
Asbestos pollution in an inactive mine: Determination of An inactive asbestos mine in Northern Greece, known as MABE, had been operational for 18 years, showing an annual chrysotile production of ∼100,000 tons.It is estimated that a total of 68 million tons of the mineral serpentine were excavated from the mine, of which 881,000 tons of chrysotile asbestos were produced.The mine deposits are loed very near to the river Aliakmonas.Minerals Free FullText Experimental Deployment of A microbial mineral carbonation trial was conducted at the Woodsreef Asbestos Mine (NSW, Australia) to test cyanobacteriaaccelerated Mgcarbonate mineral precipitation in mine tailings. The experiment aimed to produce a carbonate crust on the tailings pile surface using atmospheric carbon dioxide and magnesium from serpentine minerals (asbestiform chrysotile Mg3Si2O5(OH)4) and

One company conducted laboratory testing to recover magnesium from its dolomite deposit in Nevada and was planning to conduct a feasibility study for a proposed plant. In May, a company in Quebec, Canada, started production of magnesium from serpentine contained in asbestos tailings at itsGrowth characteristics of selected plant species on Natural revegetation on the asbestos tailings at Msauli Mine is negligible. Lack of available phosphorus, potassium and calcium, extremely alkaline conditions and surface crusting were shown to be
Accelerated Carbonation of Brucite in Mine Tailings for Atmospheric CO2 is sequestered within ultramafic mine tailings via carbonation of Mgbearing 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.黄朝晖（中国地质大学教授）_百度百科Translate this pageBin Jiang, Youguo Xu.
