Keywords scheelite fluorite calcite regulator flotation separation INTRODUCTION In scheelite flotation gangue minerals such as Fluorite and Calcite have the same surfaceactive cation Ca2 with scheelite minerals and strong binding capacity with the4526
Fluorite Flotation ProcessFluorite Flotation Separation Fluorite ore processing methods which is one roughing repeatedly choiceas a collector agent rougher with oleic acid or its substitute The process is simple lowcost advantages can be selected from the high calcium fluorite ore grade fluorite concentrate with a low content of calcium4984
Fluorite Flotation Separation Fluorite also known as fluorspar is a major source of industrial fluoride elements 20 kinds of the world one of the important nonmetallic mineral raw materials fluorite is widely used in the metallurgy of aluminum glass ceramic cement chemical industry apatite occurs as free particles and especially3422
Enhanced separation of fluorite from calcite in acidic Mar 15 2019183 Given the similarity of the surface properties of calciumcontaining minerals the flotation separation of fluorite scheelite and apatite from calcite becomes unusually difficult when fatty acid is used as collector Hu and Xu 20033880
Separation Of Quartz And Fluorite 20180515183 The crystal structure of quartz SiO 2 at approximately the same scale as the one for fluorite above Note that even though both fluorite and quartz have formulas of Send Email email protected Live Chat Get Price Send Message3193
The selection slightly soluble minerals such as Apatite fluorite scheelite calcite and mineral silicates is a relatively straightforward process However the separation of these materials from each other is difficult because of their similar surface chemical properties The method of separation by flotation of the carbonates contained4746
The main gangue minerals are quartz apatite dolomite and fluorite etc Host strata are quartzite slate limestone and dolomite Dolomite is the main host rock The orebodies are stratiform and lenticular with masses bands layers veins and disseminations4288
Grade of fluorite in this test is 3095containing CaCO3 086 On the base of much experiment research such as grinding fineness test pH test agent dosage test and so on the optimum conditions were grinding fineness for first stage is 0074mm 65pH9 sodium silicate 08 kgt and oleic acid 07 kgt The result of tests showed that the grade of CaF2 concentrate recovery and3473
Fluorite is an important strategic mineral In general fluorite ores will contain a certain amount of calcite gangue mineral Thus they need to be separated from each other For an economic separation a reverse flotation process is used to float calcite gangue from fluorite However little information on the separation is available In this study a novel reagent schedule using citric acid3841
Zhou et al 11 reported that in the flotation separation of apatite from dolomite using conventional air bubble in the presence of the collector Fatty acids the contact angles of apatite and dolomite were 725 and 670 respectively3006
Fluorite CaF2 as an important strategic mineral source is usually separated from calcite by the common froth flotation method but this separation is still not selective enough The development of a selective collector andor depressant is the key to achieving high selective separation 1Hydroxyethylidene11diphosphonic acid HEDP or H4L is widely used as an environmentally friendly3302
In this study the effect of sodium pyrophosphate NaPP on the separation of apatite from dolomite by flotation was systematically investigated Flotation results revealed that NaPP could selectively depress the flotation of apatite thus realizing the separation of apatite from dolomite Further the selective depression mechanism of NaPP was studied through zeta potential measurements3884
fluorite flotation in order to increase the separation efficiency and lower the operation costs It was 1 reported that methanoic acid could selectively adsorb onto fluorite surfaces in preference to calcite surfaces at ambient temperature This means that fluorite flotation to remove4673
For artificial mixed minerals flotation experiments the mass ratio of apatite and dolomite mineral was 11 for binary mixture The flotation process was the same as single mineral tests After the flotation process the concentrates and tailings were assayed for P and Ca The recovery of apatite was calculated based on P 2O4683
Jan 26 2017018332Global demand and consumption of rare earth elements and compounds have led to increasing research to further our understanding of their beneficiation and recovery Monazite is the secondmost important rare earthbearing mineral that can be exploited In this study the surface chemistry of monazite in terms of zeta potential adsorption density and flotation responses using4096

For example scheelitequartz or silicate type can be used in combination with gravity separation and flotation according to the particle size distribution while scheelitecalcitefluoritebarite type can be recovered by flotation The separation methods of scheelite are4315
Among the parameters affecting flotation the following are examined crystal structure solubility of minerals surface charge collectors organic and inorganic modifiers adsorption contact angle and floatability The selective separation by flotation of salttype minerals from each other and from silicates is also investigated3094
1 direct flotation process Direct flotation use effective inhibitor to control gangue mineral and collector to concentrate phosphorus in foam It is suitable for low grade phosphorus ore including magmatic rock type apatite and deposition metamorphic type apatite 2 reverse flotation process Mainly used for separation of phosphorus and3703
In this regard the flotation of barite type fluorite generally needs to adjust the pH value of the slurry through a mixing process and Na2CO3 and use oleic acid and water glass as collectors and inhibitors to obtain a mixed concentrate of fluorite and barite Ore and then flotation to separate barite and fluorite 4Beneficiation of sulfide4074
Separation of the slightly soluble minerals ksp 1010 is one of the more difficult tasks confronting flotation engineers This study focused on means of separating such prominent members of this class as scheelite fluorite and calcite from one another Some experimental work was also done on magnesite dolomite and apatite3637
