Froth flotation of scheelite – A review – DOAJ

View More

May 01, 2018 Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years. The main objective was and remains the selective flotation of scheelite from other calcium-bearing minerals, in particular calcite, fluorite and apatite

US3915391A - Recovery of scheelite from ores by flotation

View More

A flotation process for recovering scheelite (calcium tungstate) from a low grade slimey ore containing other calcareous minerals such as calcite is described. The scheelite is selectively flocculated by conditioning the ore pulp at a high pH, using intense agitation, usually prolonged, in the presence of predetermined quantities of a deflocculating agent, a source of polyvalent cations to

Prediction of Hydrophobic Reagent for Flotation Process

The test conditions of scheelite flotation were using microflotation type (50 mL) purchased from Wuhan Rock Crush and Grand Equipment Manufacture Co., Ltd. PSM samples (2 g) were placed in deionized water (conditioning time, 1 min; rotating speed, 1850 rpm; 0.25 mL of a depressant Na 2 SiO 3 (1.64 M); pH regulator Na 2 CO 3 (0.2 g); and 2 mL of

A process for separating scheelite from gange wherein the ore is ground with 0.4 to 10 grams of alkali metal carbonate per kg. of ore, forming a pulp and removing sulfide minerals from pulp liquor. Carrying out froth floatation in the presence of paraffin oil, 0.1-0.4 gram of fatty acid per kg. of ore and 3.2-5.5 grams of sodium silicate per kg. of ore wherein the weight ratio of paraffin oil

Enhanced nonferrous and noble metal recovery in scheelite

May 07, 2014 The flotation properties of new dialkyldithiophosphates (BTF-163, BTF-175) are compared with the standard basic Aeroflot reagent IMA-I413 and butyl xanthate during flotation of scheelite-sulfide ore. The selectivity of the test Aeroflot reagents in separation of chalcopyrite, magnetic pyrite, pyrite and arsenopyrite is illustrated in the article together with the option of enhanced

Effects of particle size and particle interactions on

scheelite flotation Reagent concentration and pH are two main factors determining mineral recovery. In our opinion, particle size is also responsible for scheelite flotation. To support this hypothesis, we studied the effects of particle size and fine particle ( 10 μm) percent on scheelite flotation recovery at pH 11.0 (Figs. 3 and 4)

Extraction of Tungsten from Scheelite Ore

View More

May 10, 2016 A marketable grade of scheelite is rarely, if ever, made by flotation, but an increased recovery is realized by its use and the product can be treated by soda ash solution in an autoclave. In this process the scheelite is dissolved and, by addition of lime, calcium tungsten, or “synthetic scheelite,” is precipitated. Reagent Combinations

Jan 24, 2020 The treatment of sodium oleate and flotation pulps of the main cycle when using tap water before the reagent supply enabled a certain increment in the recovery of WO 3 into the scheelite cycle concentrate, but scheelite was largely redistributed into the middling after the repurification operation. Herewith, the degree of concentration in the

Bettering tungsten supply: Effects of ceramic and cast

View More

Feb 09, 2021 Ultimately, the researchers concluded that scheelite ground by cast iron balls has a lower flotation recovery than scheelite ground by ceramic balls. They attribute this finding to the coating of iron species on the scheelite surface, which impedes adsorption of sodium oleate, a reagent that creates a hydrophobic film on the mineral surface

View More

Feb 15, 2018 Sodium silicate (or water glass) has been the most popular depressant used in the practice of scheelite flotation due to its selective suppression of calcite and fluorite . However, the biggest drawback of the application of water glass lies in the huge dosage (as much as 2–3 kg per ton of run-of-mine) required [27]

Separation by flotation of Zircon and Scheelite - Froth

So we are doing flotation of sulphides, not scheelite flotation. We use butyl potassium xanthat and T-91 reagents. We maintain pH at 2-3 in order to depress scheelite. The best solution for us would be a reagent(s) that we could add after sulphide flotation is exhausted. So we could remove zircon etc. into froth product thus cleaning scheelite
