Barite Flotation Dichromate

(PDF) OPTIMISATION OF BARITE FLOTATION PARAMETERS

Barite flotation with various collectors at different pH values. (The ciphers in parentheses indicate the consumptions in (K-dichromate) added with a 0,125 g/t consumption. The tabl es 5 and

Selective Flotation of Barite and Associated Minerals: A

2018. 3. 2. R171A (100 g/t ; pH 9) for fluorite, combined with potassium dichromate as depressing agent for quartz and barite. The final flotation treatment has led to the obtention of a barite concentrate with a 93,4% BaSO4 grade and a fluorite concentrate . with 93,6% CaF2,both answering the users’requirements.

Selective Flotation of Barite and Associated Minerals: A

Definitive choice of optimal flotation requirements focused on Petronate L (1000 g/t ; pH 6.5) for barite flotation and on Flotbel R171A (100 g/t; pH 9) for fluorite, combined with potassium dichromate as depressing agent for quartz and barite. The final flotation treatment has led to the obtention of a barite

Efficiency of Barite Flotation Reagents a Comparative Study

2016. 10. 20. is flotation. Without this technique, there would be no mining industry as it is known it today. The present work concerns a long series of tests which allowed to specify the efficiency of various collectors (anionic and cationic) and modifiers (barium chloride, citric acid, potassium dichromate,) during barite flotation.

Efficiency of Barite Flotation Reagents a Comparative

Barite is also used as mineral filler, in barium chemistry (special glasses) and in the civil engineering and public works (heavy concretes). In order to answer the requirements of this use, barite ores have to be treated and the method here applied is flotation. Without this technique, there would be no mining industry as it is known it today.

A review of water re-use in flotation ScienceDirect

1989. 1. 1. The processing technique consists of a preliminary step in which galena is floated with xanthate type collectors followed by one of the two alternatives: flotation of fluorspar with carboxylic collectors, and barite depression with dichromate and a second stage in which barite is floated with alkylsulphates or alkylsulphonates; or flotation of barite with alkylsulphates and

Examples of flotation reagent schemes for scheelite and

The gangue inhibitors of flotation wolframite are: sodium fluorosilicate, water glass, a mixture of water glass and aluminum sulfate (6: 1), dichromate, sulfuric acid and hydrofluoric acid. However, the wolframite itself can be inhibited by a large amount of oxalic acid, sodium fluorosilicate (above 4kg / t) and water glass, etc., so the amount of related inhibitors must be

In the flotation process, Xinhai mine research institute suggests that the appropriate dosage of flotation reagents should be selected according to the results of mineral processing tests. In the actual production, Xinhai mine research institute will adjust the dosage of flotation
