Red mud is a bauxite industrial waste of reddish-brown mud with high alkalinity. Red mud has relatively high silica and alumina content, so it can be utilized as a raw material in the synthesis of zeolite. This study aims to synthesize high-purity NaP zeo... see more

The object of the study is compositions of common alkali activated concretes using red mud as an active aggregate. The main problem when working with red mud is its chemical composition and high specific surface area, which quite negatively affect the pro... see more

Red mud is a generated by-product in alumina production from bauxite ore. In this study, Bintan’s red mud has been used as alumina and silica source to synthesize amorphous mesoporous aluminosilicates material. Alkali fusion method with a NaOH/red mud rat... see more

Mines in Bintan were producing bauxite for many years. The production process of bauxite to alumina produced much red mud. From X-ray Fluorescence (XRF), alumina content on Bintan’s red mud was 28.87 wt.%. This research was studying on the extraction alum... see more

Alumina extraction from red mud has been investigated by magnetic separation with three-step treatment. First, the addition of red mud with Na2CO3 (12 wt%) and heated at 110 °C for 4 h. The second step was carbon reduction using coal with mass ratio of (r... see more

The object of the study is compositions of common alkali activated concretes using red mud as an active aggregate. The main problem when working with red mud is its chemical composition and high specific surface area, which quite negatively affect the pro... see more

The utilization of red mud, which is a residue from the extraction of aluminum from mined bauxite ore, as a plant growing medium, needs to be studied further. There are some chemical aspects that may hinder the growth of, or even cause mortality in, plant... see more

Considerando que as intervenções humanas no meio ambiente são a principal causa das mudanças climáticas, o presente estudo volta-se à análise do REDD+, um mecanismo de combate ao desflorestamento que incentiva as reduções de emissões de gases de efeito es... see more

After the red mud spill in Hungary one of the risk reduction measures was to remove the deposits from the soil surface. The residual thin red mud layer was ploughed into the soil. The aim of the present 8-month-long lab-scale microcosm experiment was to e... see more
