Graphite as the most common polymorph of naturally occurring crystalline carbon is required
for many different applications such as batteries, refractories, electrical products, and …

Many reagents are used as frother in flotation process, however, a general reference for
their identification and characterization is not available. The present work categorizes the …

The depression mechanism of zinc sulfate (ZnSO 4) and sodium dimethyl dithiocarbamate
(DMDC) as the combined depressant on sphalerite was investigated by micro-flotation …

The aim of this paper is to provide geologists, metallurgical engineers, or mineral resource
strategists with a first overview of the currently available state-of-the-art knowledge of the …

Spent potlining (SPL) consists of the carbon cathodes (1st cut), aluminosilicate refractories,
and the insulation lining of Hall–Héroult cells (2nd cut) used in aluminum smelting. SPL is …

The inherent hydrophobicity of carbonaceous graphitic material enables its easy flotation
simultaneously with valuable copper sulphides, posing significant flotation separation …

In this work, the flotation recovery of sphalerite and pyrite from an old high zinc grade tailing
was studied. In particular, the effect of different flotation reagents such as collector, auxiliary …

The increase of impurities and complexity of copper ores are among the recent challenges
in the mining industry. Complex carbonaceous sulfide ores are extremely difficult to treat due …

Carbon is a common gangue, often associated with base metal ores. The hydrophobicity of
carbon causes interaction with air-bubbles during flotation, and results in carbon …

The efficient processing of base metal sulfide ores and sulfidic gold ores is sometimes
compromised by the presence of carbonaceous material (CM). One common way of dealing …
