    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

    Apr 01, 2018 · Sodium oleate (NaOl) acted as collector for scheelite. The flotation results showed that CLS had strong depressant effect on calcite flotation while exhibited little influence on scheelite flotation. Scheelite can be separated efficiently from scheelite-calcite mixed binary minerals in pH range of 7–11, when CLS was added prior to NaOl

    Apr 20, 2017 · The Pb–BHA complexes are found to be selective for the separation of scheelite and calcium minerals with little use of depressants and enable the synchronous flotation of scheelite and wolframite. Hence, a novel flotation process was developed for the recovery of tungsten minerals

    Scheelite is a kind of easily slimed mineral. In the grinding process of scheelite, a large number of fine slimes can be produced, which seriously affects the flotation efficiency of scheelite [ 1 ]; this is because many calcium-bearing minerals (fluorite and calcite) exhibit similar surface properties to scheelite
