The Definitive Guide to Flotation Separation Fote

2021-6-8  What is flotation separation The flotation separation mainly refers to froth flotation, which is based on the difference in physical and chemical properties of the surface of minerals, using the buoyancy of bubbles in the ore pulp to achieve separation.

2012-3-1  DTAC is not suitable for the flotation separation of scheelite from the other two calcareous minerals. Using DDDAC the flotation recovery of scheelite is higher than the calcite and fluorite recovery when the pH is lower than 8.7. The flotation recovery of scheelite decreases at pH values above 8.7 (see Fig. 2). Over the pH range from 7 to 8, the difference in flotation recovery between scheelite and the other two calcareous minerals

Flotation separation of minerals LAKE SHORE MINES

This invention relates to the flotation method for the separation of minerals and is more particularly directed to the conditioning of the mineral pulp to be subjected to flotation in order to overcome the effect of constituents of the pulp which hinder flotation.

US5047144A Process for the separation of minerals

The present invention provides a process for the separation of minerals by flotation in the presence of activators and suppressors. Activators are cation-active condensation products and suppressors are anion-active products of aminoplast formers, formaldehyde and amines, ammonium salts, acids or a sulphite, in combination with either an anion-active or cation-active tensides.

US6036025A Mineral flotation separation by

A process for the separation of minerals of different mineralogical character. The process involves conditioning a milled slurry or a slurry of a flotation concentrate which contains a mixture of valuable sulfidic minerals and non-sulfidic gangue material with an inert/non-oxidizing gas and/or a reducing/deoxifying agent. The conditioning is conducted to achieve a controlled dissolved oxygen

Flotation separation of smithsonite from calcite by

2021-6-15  Flotation separation of smithsonite from calcite is difficult due to the complex associated relationship between smithsonite and calcite, the surface properties are similar and calcite has good natural floatability. Flaxseed gum (FG), a natural pollution-free extract, was used as a kind of selective depressant firstly for flotation of smithsonite.

Flotation separation of chalcopyrite from galena by

2016-1-20  In the separation of copper/lead minerals by flotation, APS can be used as the depressant of galena. The effects of APS on the recovery rates of chalcopyrite and galena at pulp pH=6.5 were determined (see Fig. 5). The results indicate that with the increase of APS concentration from 0 to 200 mg/L, the floatabilities of both minerals remain
