The graph above shows the buffer capacity changes in 0.1 M of an acetic buffer. As expected, the buffer resists acid and base addition to maintain an equimolar solution (when pH=pK a).From the graph, it is obvious that the buffer capacity has reasonably high values only for pH close to the pK a value: the further from the optimal …

1. Introduction. Red mud, the bauxite residue of the alumina refining process, is usually stockpiled in storage. Red mud can generate hyper-alkaline leachate (bauxite liquor), which has high ionic strength and multiple heavy metals (such as As, Pb, and Zn) (Sun et al., 2019).Consequently, bauxite liquor may increase the risks of …

In this process, the raw bauxite which is mixed is converted to calcined bauxite. The following reaction takes place Al2O3.2H2O → Al2O3 + 2H2O (at 1300 deg.) Other materials that can be calcined in this unit are clay, fireclay, etc. The calcination unit can be divided into 5 parts: Raw material crushing and storage.

A simple and practical method for the synthesis of zeolite 4A from bauxite tailings is presented in this paper. Systematic investigations were carried out regarding the capacity of zeolite 4A to remove Cr(III) from aqueous solutions with relatively low initial concentrations of Cr(III) (5–100 mg·L−1). It is found that the new method is extremely …

Bauxite is not a mineral but a rock with minerals in it. It is a clay-like substance which is pinkish, whitish or reddish in color depending on the amount and type of impurities. It is soft and, when struck with a hammer, does not produce a metallic sound. Its specific gravity is generally around 2.6 and it has a Mohs hardness of 1 to 3.
