Froth Flotation of Tungsten Ore

Scheelite (CaWO4) and Wolframite ((Fe,Mn)WO4) are the principal minerals of tungsten, but other important minerals include ferberite (FeWO4) and huebnerite (MnWO4) will also respond to froth flotation.The high specific gravity of these minerals makes many of these ores amenable to gravity concentration methods, however, the fine dissemination of mineral in gangue for some ores may

Extraction of Tungsten from Scheelite Ore

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

US4488959A Scheelite flotation process Google Patents

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, 0.10.4 gram of fatty acid per kg. of ore and 3.25.5 grams of sodium silicate per kg. of ore wherein the weight ratio of paraffin oil

Froth flotation of scheelite A review ScienceDirect

The classic way to go it the lime flotation process involving lime, sodium carbonate as a copH modifier, a fatty acid as a collector (usually sodium oleate) and sodium silicate as a depressant for the gangue. Scheelite flotation has run into serious difficulties when it requires separation of scheelite from a carbonaceous gangue.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Scheelite flotation production line,Scheelite Processing

Scheelite ore has good floatability, usually caused by the presence of calcium gangue minerals, which makes flotation process more complex. In order to improve the selectivity of flotation process, by adding metal salts, can improve scheelite flotation effect significantly.
