Due to environmental issues and the restrictions imposed on mineral flotation separation,
the use of biodegradable and environmentally friendly reagents has gained widespread …

The low-grade ores invariably liberate in finer sizes and the fines contain good amount of
iron values in it. Flotation is the most established solution, both technologically and …

While flocculant type and concentration have been extensively reported in the literature for
sedimentation of iron ores and its respective mono-minerals, little information is known …

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be
performed in two technical routes: direct flotation of iron oxides and reverse flotation of …

Adsorption mechanism of mixed cationic C12 amine and anionic sulphate/oleate collectors
was investigated on hematite through Hallimond flotation studies. The flotation response of …

Most iron reserves are low in grade with quartz as the main gangue mineral, and anionic
reverse flotation has become the most crucial separation method in the processing plants of …

Cationic flotation is one of the most widely accepted technologies for upgrading siliceous
iron ore using polysaccharides (mainly starches) as depressing agents for iron bearing …

The consumption of iron ore has increased rapidly over the past decade due to the
tremendous growth of the iron and steel industry. The depletion of high-grade iron ore …

Electrochemical processes involving particle suspensions are still ill understood. Electro-
flotation is process through which particles or ions can be selectively separated. Although …

A slagheap of the Jarada coal mine (Morocco) was recycled using the following ore
processing operations: sifting, gravimetry and flotation. This abandoned coal mine has …
