Different Types of Fluorite Separation Methods

18/11/2020  1. Quartz Type Fluorite Beneficiation. Quartz-type fluorite ore is mainly composed of fluorite (with a content of up to about 85%) and quartz. There are only a small amount of calcite, barite and sulfide. The key to its separation is mainly to reduce the silicon in the concentrate.

The Role of Water Glass in the Flotation Separation of ...

However, the flotation separation of fluorite from quartz using water glass is not so effective, as there is always a small amount of fine quartz (less than 10 μm) in the fluorite concentrate. The floated fine quartz in fluorite concentrate has been reported to be the result of metal ion activation on the fine quartz that defeats the depressant effect of the water glass [ 13 , 14 , 15 ].

Froth flotation of fluorite: A review - ScienceDirect

01/04/2021  Quartz-fluorite separation. Quartz is often associated with fluorite . The critical step for quartz-fluorite separation is grinding, to fully liberate quartz and fluorite and at the same time to avoid overgrinding [110,160]. Two grinding stages are usually implemented. After the first grinding stage, a rougher flotation is launched, and then the concentrate will undergo a second grinding stage, followed

The Role of Water Glass in the Flotation Separation of ...

Fluorite is the principal mineral of fluorine and usually coexists with quartz in deposits. The removal of fine quartz in fluorite concentrate is the main problem in fluorite flotation. In this study, the flotation tests on fluorite, quartz and a weight equivalent mixture (all less than 10 μm) using water glass (with different modulus) as depressants and sodium oleate as collector were conducted.

Fluorite (Fluorspar) Flotation Process - Xinhai

Separation of fluorite and quartz. The fatty acid collects fluorite (fluorspar), and sodium silicate restrains quartz. The dosage of sodium silicate should be controlled properly; a small amount has activation to the fluorite, but inhibition function is not enough; excessive inhibits fluorite (fluorspar). Sometimes in order to increase the inhibitory effect of sodium silicate on quartz, some ...

How to Process Fluorite? - Mining-pedia

24/12/2019  Fluorite flotation separation between fluorite and quartz. Using the fatty acid as the collector to collect fluorite ore, and sodium silicate as the inhibitor to inhibit quartz in the fluorite beneficiation process. Less amount of sodium silicate will cause worse inhibition effect, but activates fluorite in the fluorite flotation process. However, over sodium silicate will inhibit fluorite ...

3.Separation of fluorite and quartz: Fluorite is captured with fatty acids, water glass is used as a quartz inhibitor, and sodium carbonate is used to adjust the pulp pH to 8-9. The quantity of water glass should be controlled well. When there is a small amount, it will activate fluorite, but the inhibitory effect on quartz will be insufficient. If the amount of water glass is excessive, the ...

How is Fluorite Mineral Extracted? - Xinhai

26/07/2019  For the flotation separation of fluorite mineral and quartz, the pH value can be controlled between 8-9 by Na2CO3. Water glass inhibits quartz, but need to control the amount of water glass, too much will inhibit fluorite mineral. In order to improve the selectivity and inhibition of sodium silicate, some iron salt and aluminum salt were added, and then fluorite mineral was flotation by fatty ...
