Leaching behaviour of elements and evaluation of pre-treatment methods for municipal solid waste incinerator residues in column leaching tests.
Two new pre-treatment methods (water-washing/carbonation and carbonation/phosphate stabilization) of municipal solid waste (MSW) incinerator residues were evaluated by column leaching tests under aerobic conditions and anaerobic conditions (which were changed to aerobic conditions after 10 months). A mixture of bottom ash and fly ash (5:1 ratio) was pre-treated using each method. Shredded incom...
متن کاملRemoval and Recovery of Uranium from Solid Wastes by Supercritical Carbon Dioxide Fluid Leaching Method
Supercritical CO2 fluid leaching (SFL) method using supercritical CO2 fluid containing a complex of HNO3 tri-n-butyl phosphate (TBP) was applied to removal of uranium from radioactive solid wastes. Sea sands, incineration ashes and porous alumina bricks were employed as matrixes of simulated solid wastes. Real radioactive incineration ash wastes and firebrick wastes were also subjected to the S...
متن کاملComposting of Municipal Solid Wastes
The generation of municipal solid waste is increasing year by year and there are many options for handling and disposing of these wastes. Currently in United States land disposal is the most common practice to deal with municipal solid wastes. The evolution of waste generation, and increase in population suggest composting as a future alternative. Since municipal solid waste comprises of a high...
متن کاملLeaching of Gold and Silver from Crushed Au-Ag Wastes
Au-Ag noble metal wastes represent a wide range of waste types and forms with various ballast elements and components. The thiourea process of gold and silver extraction from ores, concentrates or secondary raw materials consists of gold and silver leaching into the thiourea solution and the consequent precipitation of these metals from the solution. Due to the non-toxic character of thiourea i...
متن کاملCurrent Research Trends of Microbiological Leaching for Metal Recovery from Industrial Wastes
The concept of microbiological leaching have played a greater role to recover valuable metals from various sulfide minerals or low grade ores during the middle era of twentieth century and that continued till the end of the century. Slowly, due to depletion of ore/minerals, and implementation of stricter environmental rules, microbiological leaching process has been shifted for its application ...
