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 …

As a common gangue in many mineral flotation processes, the activation of quart by
inevitable cations will worsen the flotation separation of valuable minerals from quartz. In …

In this paper, the flotation separation of quartz and feldspar was studied with CaCl 2 as
activators and mixed sodium oleate/dodecylamine (NaOL/DDA) collectors under alkaline …

Since the preferential dissolution of hydroxyl ion, serpentine is positively charged under
weak alkaline conditions, and easily covers on sulfide minerals through electrostatic …

Separating fluorite and calcite through flotation is difficult due to their similar Ca 2+ sites on
the adsorption surface of collectors. Psyllium seed gum, a reagent naturally derived from …

Fine particle flotation is carried out in a flotation column with a 19-channel ceramic
membrane sparger. The microbubble generation is controlled by the shear flow in the …

Fluorite ore, as an essential raw material in the fluorinated chemical industry, required
effective separation and purification. The removal of impurities such as quartz becomes the …

A novel pH-responsive flocculant, P (AM-DEA-DPL)(PADD), was first used for efficient
separation and recovery of Cu and Mo from secondary resources via selective flocculation …

The flotation separation between sulfides and fine serpentine has always been a difficult
problem due to their hetero-coagulation. To acquire a better understanding on the adverse …

An innovative approach of clean utilization of waste oil is proposed to reduce the risk of
environmental pollution and achieve cleaner production of fluorite. The waste oil in kitchen …
