The concept of a “low-carbon economy” will drive the accelerated deployment of clean
energy technologies, which, in turn, will lead to rapid growth in demand for metal resources …

Mining has advanced primarily through the use of two strategies: pyrometallurgy and
hydrometallurgy. Both have been used successfully to extract valuable metals from ore …

The flotation of diasporic bauxite is to separate diaspore (valuable mineral) from
aluminosilicate minerals (gangue minerals, mainly including kaolinite, illite and pyrophyllite) …

Reverse cationic flotation is the most known beneficiation method for the separation of fine
hematite particles from silicates. In this process, the depression of the hematite surface is an …

Kaolinite is one of the main associated minerals (gangue) in the processing of diasporic
bauxites. Sulfuric acid pretreatment has been shown to have an improving effect on kaolinite …

Efficient utilization of high-silica bauxite and minimization of bauxite residue are of great
significance for the sustainable development of the alumina industry. In this paper, a novel …

In this paper, oleate sodium (NaOL) and benzohydroxamic acid (BHA) was introduced as a
mixed collector for diaspore ores. The flotation behavior and the adsorption mechanism of …

Bauxite is the main raw material of the alumina industry. However, high-sulfur bauxite
constitutes a relatively large proportion of bauxite resource in China. Excessive sulfur …

Surface pretreatment on minerals prior to flotation was proved to increase the selectivity of
separation process. Organic acid pretreatment of low-grade diasporic-bauxite was …

Mixed collectors were widely used in mineral flotation. In this work, D-phenylalanine (D-phe)
was first introduced to improve the collectability and selectivity of sodium oleate (NaOL) for …
