The generation of bauxite residue, the by-product of alumina manufacture from bauxite ore,
has increased to a global stockpile of some 3 billion tonnes. In the absence of significant …

Bauxite residue, a highly alkaline solid waste, is extremely hazardous to the surrounding
environment and current research approaches have largely focused on the removal and …

Alkalinity regulation and nutrient accumulation are critical factors in the construction of plant
and microbial communities and soil formation in bauxite residue, and are extremely …

Historically, tailings management plans have focused largely on confinement and
containment, with little regard to long term alteration of the chemical, physical, and biological …

Tailings are artificial soil-forming substrates that have not been created by the natural
processes of soil formation and weathering. The extreme pH environment and …

Bauxite residue, the by-product of the alumina industry, is mainly stored in land-based
bauxite residue disposal areas (BRDAs). Environmental concern has been raised due to the …

Large amounts of fossil fuel combustion wastes (eg fly and bottom ash) are discharged on
land surface all over the world. The uppermost layer of disposal sites is subject to soil …

Forestry reclamation practices have been very popular in the second half of the last century,
and many spoil heaps have been converted into forests since. In our experiment, three forest …

This study was based on the premise that Technosols constructed under tropical conditions
are a valuable tool for inexpensive mine reclamation programs. These anthropogenic soils …

The overwhelming production of waste represents a complex environmental challenge for
mining companies worldwide. Efforts are currently being made to develop methods for …
