·The fly ash sample employed in this study was collected from the fly ash precipitation system at the Xinwen coal combustion power plant in Shandong province in three different periods of time to ensure the representativeness of the sample The products after decarburization can be used for building materials road construction material and
·Fly ash FA is a complex and Therefore with the decarburization process fulfilled not only can the separated UC be recycled elsewhere but the leftover ash will find its way Flotation has been proven to be an effective separation technique aimed at the removal of UC from FA [16] This process mainly utilizes the differences in the
·The chemical compositions of fly ash waste lime as well as the primary lime used as reference are shown in Table 3 It is seen that the CaO contents in fly ash and waste are respectively % and % which are lower than that in the primary lime CaO content % The XRD analysis results of fly ash and waste lime are shown in Fig 2
·The company was an amalgamation of several players in the fly ash industry such as fly ash marketer Headwaters Inc a 2016 merger for $ billion and JTM among others Combined Boral
·To promote the widespread use of fly ash FA and coal gasification slag CGS in mine filling reducing the amount of cement and promoting the sustainable development of mining enterprises are essential In this study decarbonized CGS DCGS was prepared from CGS through decarbonization A new DCGS FA filling material was prepared using DCGS FA
·Key words Fly ash Waste treatment Preconditioning energy input Fluid intensification Flotation Kinetic modeling ： Fly ash FA is a complex and abundant solid waste created by humans and has caused environmental issues for which flotation is an effective technique employed before its comprehensive However the complex and
·Fly ash and lime by products are the two main waste streams generated by the pulp and paper industry Traditionally these wastes are disposed of either in surface impoundment or landfills Greater environmental concerns and limited land availability have made these disposal practices increasingly unacceptable and costly Thus the objective of this study

·with the mixture ratio of 3 7 is superior to the other surfactant mixtures in decarburization and PCDD/Fs removal and can remove % of carbon constituents and % of PCDD/Fs fly ash are enriched in UC during incineration [4] Every gram of PAC can absorb 105 115 ng PCDD/Fs so the adsorption capacity of PAC is remarkable [5] Therefore
