·Red mud is a secondary resource which contains many kinds of minerals Main chemical compositions contained in red mud are Fe 2 O 3 Al 2 O 3 SiO 2 TiO 2 CaO Na 2 O and K 2 O which account for more than 75% In addition a small amount of rare metals such as Ga Ge Sc etc also exist in red mud [] Simultaneously maximize the value of recovery and
·MSWI FA and red mud are hazardous materials that need to be treated urgently Coal based reduction process is one of the resource utilization technologies for waste materials containing metals Therefore the present study proposed a novel method called co reduction process to realize the collaborative utilization of MSWI FA and red mud

·Red mud is a highly alkaline solid waste discharged in the alumina production process Because of its large amount of discharge and high alkalinity it is mostly stored in dams occupying a large
·Red mud RM is a solid waste generated during the process of alumina production RM has already posed a serious environmental threat with the development of the alumina refining industry The comprehensive utilization of RM has attracted much attention due to its large scale generation and harmful nature
·An integrated technological route for comprehensive utilization of red mud through the extraction of valuable components and reuse of the magnetic residue is proposed In this study inductively coupled plasma atomic emission spectroscopy X ray fluorescence X ray powder diffraction and vibrating sample magnetometer were used to characterize
·Abstract Red mud and phosphogypsum are staple solid wastes with considerably large annual emissions Improving their comprehensive utilization is the key to addressing the large accretion of both red mud and phosphogypsum They have great utilization potential and can be collectively modified to expand the utilization field and increase the
·growth rate of about 50 million tonnes but China s red mud utilization rate is only 4% Most of the currently produced red mud is still dealt with by storage on land The stock piling of red mud not only causes a waste of resources and occupies a lot of land but also destroys the surrounding environment red mud dam which brings serious
The comprehensive utilization of RM has attracted much attention due to its large scale generation and harmful Red mud RM is a solid waste generated during the process of alumina production RM has already posed a serious environmental threat with the development of the alumina refining industry The comprehensive utilization of RM has
·Red mud is a common solid waste produced during the industrial production of alumina from bauxite The amount of red mud discharged per ton of alumina produced varies depend on the ore grade production methods and technological levels with an estimated range of to tons [1] Red mud is commonly disposed through stacking which can cause soil
