The present work shows the results of X ray diffraction XRD Fourier transform infrared FTIR and thermal analysis of untreated RMnt and acid treated red mud RMa a bauxite ore processing waste exchanged with Pb2 Cd2 and Zn2 cations These studies were performed in order to investigate the changes in the sorbent structure caused by the
Bauxite residue known as red mud is a by product of alumina production using the Bayer process Currently its total global storage amounts to over billion tons including about 600 million
The European Training Network for Zero Waste Valorisation of Bauxite Residue REDMUD therefore targets the vast streams of new and stockpiled BR in the EU 28 BR contains several critical metals is associated with a substantial management cost whereas spills have led to major environmental incidents including the Ajka disaster in Hungary
25 October 2011 The International Seminar on Bauxite Residue red mud recently finished in Goa India and was a success The seminar was held from 17 to 19 of October and was structured around 3 areas characterization co ordination by Frank Feret Rio Tinto Alcan and Peter Smith CSIRO processing storage and storage area rehabilitation co ordination by Vinod Sood

Managing red mud RM a solid waste byproduct of the alumina recovery process is a serious ecological and environmental issue With 150 million tons/year of RM being generated globally nearly billion tons of RM are presently stored in vast waste reserves RM can be a valuable resource of metals minor elements and rare earth elements The suitability
High iron bauxite IRB red mud RM and fly ash FA are resources rich in iron and alumina yet there are no effective methods of recovering and utilizing them In this paper a new reduction smelting technology for the extraction of iron and alumina from IRB RM and FA is proposed based on the technology platform of Slag Metallurgy Mineral Recycling and Resource
Red mud is the by product of alumina production following extraction of the metal from bauxite ore via the Bayer process The production of one ton of alumina generates approximately tons of red mud depending on the grade of bauxite Pascual et al 2009 At the Pingguo alumina refinery in China one ton of alumina usually yields one ton of
1 Introduction Red mud is the industrial waste generated during the production of alumina According to the grade of raw material bauxite and the production process of alumina red mud can be divided into Bayer red mud and Sintering red mud [1 2] Based on present technologies there is t red mud generated by each 1t alumina produced [] It is
Bayer red mud is derived from the Bayer cycle the major industrial approach to producing alumina from bauxite The chemical and mineral composition of Bayer red mud varies greatly with respect to the type of bauxite ores and processing parameters Bayer red mud from Guizhou China was investigated using XRF ICP MS and XRD The mineral composition of
The above chemical analysis of the Birac Alumina Industry red mud indicates an expected high percent of compound Fe2O3 % and high silica % and Al2O3 % The high loss of Al2O3 through the bauxite processing suggests inadequate mineral liberation in milling grind fineness
Red mud RM is a highly alkaline by product produced by the aluminium industry The total stockpile of RM in the world is evaluated to be close 4 billion tons which caused serious soil and water pollution The use of RM in masonry materials has proven to be a prospective strategy to alleviate the environmental problems caused by RM During the past
