Fluorite, as a scarce non-renewable strategic non-metallic mineral resource, is the primary
raw material for fluorine products used in diverse fields such as metallurgy, national …

Pyrite is a gangue mineral widely associated with valuable minerals. It is problematic to deal
with in differential flotation because it easily reports to flotation concentrates. Pyrite may float …

Chlorite, as the most representative gangue mineral associated with specularite, of which
the separation of these two minerals is difficult. This paper investigated the depression effect …

ABSTRACT A tremendous amount of research has been done on refining the flotation
process for iron ore and designing the reagents which go into it. This paper reviews the …

Polysaccharides are some of the most widely employed flotation reagents in the mineral
processing industry. Among several, starch is of particular importance for reverse flotation of …

Froth flotation has been a commonly employed technique to enrich natural ores by removing
impurities based on the surface properties of minerals. This process involves the use of …

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

Flotation is one of the most effective methods to selectively separate refractory hematite from
quartz. However, the separation mechanism of the hydrophilic minerals of hematite and …

Hematite is commonly upgraded in China using a reverse anionic flotation process with
starch as depressant for hematite, Ca 2+ as activator and fatty acids as collector for quartz …

Various starches have been used as depressants in reverse flotation of iron ores. To date,
the effect of molecular structures of starches on the depressing behavior is still not clear …
