Flotation separation of smithsonite from quartz using ...

Flotation separation of smithsonite from quartz is difficult due to the dissolved zinc species activated the quartz flotation. To solve this problem, calcium lignosulphonate (CLS) was introduced as a depressant for quartz in smithsonite flotation when …

Mechanism of separating muscovite and quartz by …

Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC). The adsorption mechanisms of these three kinds of amines on muscovite and quartz were studied by FT-IR spectrum analysis, contact angle …

In this work, fine magnetite was used as a magnetic seed to enhance the separation efficiency of fine hematite from quartz during reverse micro-flotation.

(PDF) Separation of Feldspar from Quartz: Mechanism of ...

Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse ...

Selective Flotation of Quartz from Hematite by Amide …

The quartz recoveries at pH 10.5 with amide-amine were higher than those with etheramine in all the tested concentrations. At pH 10.5, the selective window in flotation of quartz from hematite was of 80%. The presence of secondary amide in the chemical formula of the reagent was identified through amide-amine infrared spectrum analysis.

Selective flotation of smithsonite, quartz and calcite ...

Abstract: The flotation separation of smithsonite from calcite and quartz using a alkyl diamine ether (GE−609) as the collector was investigated through micro-flotation experiments and the real ore flotation experiments. The results show that GE−609 exhibits good collecting capability to three minerals without selectivity.
