Scheelite flotation Afuruika
Schescheite CaWo4 containing 380.6% of Wo was collected by fatty acid and its soap in flotation. Sodium carbonate is commonly used as pH regulator.When using fatty acid as collector the optimum pH is 9~10.Inhibitors can be water glass dextrin starch and so on.Although scheelite is good in floatability from the economic point of view the recovery of coarse scheelite is usually by redoing

acid as a collector and 75 g/t of K8300 as a frother. Cleaner flotation is a process to float scheelite only for producing a high grade concentrate as possible without the addition of any reagent. Furthermore a locked cycle test was carried out based on these results to calculate material balance to provide a design of a continuous pilot plant.

Scheelite flotation previously captured xanthate sulfide minerals the float scheelite plus a small amount of oxide sulfide sulfide leak not suppress a small amount. 4. White tungsten and quartz silicate separation. Oleic acid as collector water glass as inhibitors can inhibit the quartz and silicate gangue surfaced scheelite. Case
The flotation separation of scheelite from calcite and
1. Introduction. Scheelite (CaWO 4) is a typical tungstate mineral and usually coexists with other calciumcontaining minerals such as calcite (CaCO 3) and fluorite (CaF 2) in deposit.By now flotation is the most commonly used technique to separate scheelite from calcite and fluorite. Long chain carboxylic acids such as fatty acids and their derivatives are the most typical collectors in
Examples of flotation reagent schemes for scheelite and
In the scheelite deposit there are often some symbiotic minerals (such as tin molybdenum etc.) these symbiotic minerals will enter the scheelite concentrate during the reelection process affecting the quality of the concentrate therefore in the flotation of scheelite There is also the problem of separation of tungsten tin and tungsten molybdenum.

The separation of scheelite and barite. It is difficult to separate scheelite and barite by sodium silicate because of the closed inhibitory action for scheelite and barite. We choose alkyl sulfate as collector to repeatly select barite under the 1.53PH and the product in tank is scheelite. The separation of scheelite and sulfide
Selective flotation of scheelite from calcium minerals
The results of the batch flotation tests on mixtures of these minerals showed that the recovery of scheelite from scheelitesilicate mixtures (31% WO 3) with (NaPO 3) 6 or Na 4 P 2 O 7 increased by 20% as compared with sodium silicate and the WO 3 grade of the concentrate by 5%. At room temperature the scheelitecalcium mineral mixtures could not be separated with sodium silicate.

Selective flotation of scheelite from calcite and fluorite
The 4:1 collector mixture 733+MES with WG (3.0 × 10 3 mol/L) at pH 10 could achieve selective flotation of scheelite from fluorite and calcite. With a lower cost lower dosage higher selectivity and higher tolerance against water hardness the collector mixture 733+MES exhibits great potential for industrial application in scheelite flotation.
Investigations on flotation separation of scheelite from
In scheelite flotation fatty acids and their derivatives are the most commonly used collectors. However due to the same active Ca 2+ species on the cleavage surfaces of scheelite and calcite the two minerals often exhibit similar reactivity to these fatty acids collectors which causes poor selectivity in flotation (Pradip et al. 2002).
