Abstract In this study, red mud was used as a raw material to extract Al and Fe using hydrochloric acid. A highly efficient polyaluminium ferric chloride (PAFC) flocculant was prepared by adjusting the pH of a leaching solution, the molar ratio of Al to Fe, and the polymerisation temperature.

High performance polymeric aluminum silicate sulfate (PASS) flocculant from abandoned molecular sieve | Environmental Science and

Cheng et al. extracted Al and Fe from red mud to synthesize polyaluminum ferric chloride (PAFC) flocculant, resulting in an impressive 82.6% removal rate for total organic carbon. Many manufacturers use industry-grade ores as raw materials for the preparation of inorganic polymer flocculants (Sun et al. 2011 ).

Mechanical dewatering of red mud - ScienceDirect

Red mud is a by-product of alumina extraction from bauxite ore. It contains high quantities of alkali, minerals, and metal ions, which are typically pumped as thick slurry to a residue disposal area. Dry cake disposal is the most preferred technique for the disposal of red mud, which reduces the environmental impact.

Red Mud from the Aluminium Industry: Production, Characteristics, and Alternative Applications in Construction Materials¡ªA Review - MDPI

About 120 million tons of red mud is produced worldwide each year. Due to its high basicity and potential leaching, its storage is a critical environmental problem. This material is typically stored in dams, which demands prior care of the disposal area and includes monitoring and maintenance throughout its useful life. Consequently, it is crucial to figure out an industrial solution able to

Because the red mud residue with small particles is quite difficult to be settled during the Bayer process, flocculants, which are ultrahigh molecular weight water soluble polymers, are often used to improve red mud settling rate and facilitate the solid?liquid separation [1?3].

Red mud is piling up. Can scientists figure out what to do with it?

This brownish red slurry, a caustic mishmash of metal- and silicon-rich oxides, often with a dash of radioactive and rare earth elements, is what's left after aluminum is extracted from ore. And it is piling up. Globally, some 3 billion tons of red mud are now stored in massive waste ponds or dried mounds, making it one of the most abundant

In the alumina production, the red mud is obtained after the autoclave leaching of the milled ore. The red mud here is to be washed away of some valuable aluminate solution, most of all in the open-loop counter-current configuration with a completed washing cycle in thickeners [1, 2, 3].
