2020/1/1· Petrov’s process is complex, costly and difficult to control. • Scheelite was selectively separated from fluorite using Pb-BHA complexes. • Adsorption mechanism of Pb-BHA complexes was studied. • A simplified flotation process was developed. • New process isCited by: 16
2018/5/1· They were also able to use this process in the Shizhuyuan processing plant, improving the scheelite and wolframite recovery by almost 10% and dividing the consumption of sodium silicate by 25 , . Lead nitrate was used in combination with sodium silicate, sodium carbonate and a collector to achieve a 96.18% scheelite recovery and 6.15% grade for a feed grade of 0.86% on a Jiangxi ore by Wu et ...Cited by: 89
Crystal StructurePhysical PropertiesOriginApplicationsOccurrenceScheelite is a calcium tungstate mineral that is the dominant member of a solid solution series between tungsten-rich scheelite (CaWO4) and rare molybdenum-rich powellite (CaMoO4), a much less common variant. This solid solution explains why most scheelites contain certain amount of molybdenum in their structure. Scheelite crystallizes in the tetragonal system, often forming as tetragonal dipyramids which look like octahedrons. Additionally, it may be tabular, massive, granular or columnar, sometimes
2017/4/20· Pure calcite, scheelite, wolframite, and fluorite were sourced from Shizhuyuan Mine, Hunan, China. Powder XRD data confirm that the purities of scheelite, fluorite, and calcite minerals are higher than 97%. The fractions finer than 74 μm were used for flotationCited by: 29

This study presents a highly selective reagent system that utilizes sodium hexametaphosphate (SHMP) to improve the separation of scheelite from calcite and fluorite using an anionic–nonionic collector. The recoveries of calcite and fluorite decreased to 20% as the SHMP dose exceeded 6 × 10−6 mol/L, whereas that of scheelite remained at 85%. The interaction mechanisms of ...Cited by: 4
Oleoyl sarcosine is used as a selective collector both in the flotation of fluorite in calcitic gangue  and of scheelite in siliceous gangue [19,53]. Its selectivity for scheelite against ...
The addition of ferrous sulfate as a depressant for Ca-bearing minerals such as calcite and fluorite during scheelite flotation was investigated to recover scheelite from tungsten mine tailings, using Hallimond-tube flotation tests, zeta-potential measurement and Fourier-transform infrared (FT-IR) analyses. The flotation tests indicate that the selectivity of scheelite recovery was the largest ...Author: Moon Young Jung, Jay Hyun Park, Kyoungkeun Yoo
2018/5/2· Fluorite, Yaogangxian Mine, Yizhang County, Chenzhou Prefecture, Hunan Province, China Fluorite Scheelite Blue Fluorite with Phantom Purple Fluorite from England. (public display, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA) Fluorite is a halide mineral with chemical formula is calcium fluoride (CaF2).1
