Experimental study on floatation of scheelite ore of Jiangxi
TLDR
In this paper, the scheelite was concentrated by adopting the full flotation process with sodium carbonate as regulator agent, sodium silicate as inhibitor for gangue minerals, lead nitrate as activator and ZL pharmacy as collector.Abstract:
In this study, according to the characteristics of scheelite in run-of-mine, the scheelite was concentrated by adopting the full flotation process with sodium carbonate as regulator agent, sodium silicate as inhibitor for gangue minerals, lead nitrate as activator and ZL pharmacy as collector. 6.15% of the coarse scheelite concentration with tungsten recovery of 96.18% was obtained from the raw ores with grade of 0.86%. The concentration of rough tungsten by heating, by which the high-quality scheelite with tungsten of 62.31% and tungsten concentrate recovery of 93.53% was obtained.read more

Froth flotation of scheelite – A review
Nathalie Kupka,Martin Rudolph +1 more
TL;DR: Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years as discussed by the authors. But due to similar properties, most attempts have limited success or only specific application (linked to a type of ore or a location).

Investigation of the depressants involved in the selective flotation of scheelite from apatite, fluorite, and calcium silicates: Focus on the sodium silicate/sodium carbonate system
TL;DR: In this paper, the effect of adding metallic cations [FeSO4, Al(NO3)3, and Zn(SO4)] prior to sodium silicate was investigated.

Role of sodium carbonate in scheelite flotation – A multi-faceted reagent
Nathalie Kupka,Martin Rudolph +1 more
TL;DR: In this article, a multi-faceted reagent, which serves as a buffering pH modifier, a pulp dispersant precipitating calcium ions in suspension and a depressant for calcite and calcium-bearing silicates, is presented.
