2016-9-8  The flotation results of single mineral and mixed binary minerals demonstrated a high selectivity and recovery for the flotation of scheelite from calcite at pH 7 using mixed DDA/NaOL collectors. The adsorption mechanism of the selective separation was analyzed through zeta

Flotation Separation of Scheelite from Calcite Using

Scheelite was floated from a low-grade (0.28 per cent W03) calcitic (96.30 per cent CaCO3) scheelite ore using oleoyl sarcosine as collector and alkylated 8-hydroxyquinoline as modifier. Compared to oleoyl sarcosine alone, the grade and the recovery of scheelite concentrate were increased from 8.07 per cent to 33.54 per cent and from 55.1 per cent...

Selective flotation of scheelite from calcite using calcium

2018-11-20  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.

The flotation separation of scheelite from calcite and fluorite

2018-11-20  Dextran sulfate sodium exhibited a selective depressant effect on calcite and fluorite flotation when it was added before sodium oleate. Using dextran sulfate sodium as depressant could achieve the preferential flotation separation of scheelite from calcite and fluorite by

Flotation separation of calcareous minerals using

The flotation separation of scheelite from fluorite and calcite using dodecyltrimethylammonium chloride (DTAC), dodecyldimethylbenzylammonium chloride (DDBAC), or didodecyldimethylammonium chloride (DDDAC) as the collector has been investigated.

An Overview of Calcite Recovery by Flotation

In some ores, calcite is present in moderate quantities along with silicates. In such cases, silicates or sulphides associated with calcite are floated using amine surfactants (Hanna 1975).All these experiments were performed at alkaline pH; if silicates or sulphides were present in the ores, these were floated before the separation of scheelite and calcite was performed.

Interactive effect of minerals on complex ore flotation:

The separation of scheelite from calcite and fluorite by using flotation, and the efficient recovery of fine scheelite particles has been a tough problem in mineral processing. Difficulties in separation are attributed to the similar flotability and interactive effects among different minerals with different particle sizes, which seriously

[PDF] Selective Flotation of Calcite from Fluorite: A

2021-2-7  Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using citric acid
