Barite-calcite-fluorite type fluorite ore separation process flow

As an important non-metallic mineral resource, fluorspar is widely used. With the deepening of development, the development of associated fluorspar ores is becoming more and more important. Among them, the physical chemistry of several minerals of calcite-barite-fluorite type fluorite ores The properties are similar, but the particle size is generally finer. It is a fluorspar ore that is difficult to select and is often separated by flotation.

In this article, we will discuss how to select barite-calcite-fluorite type fluorite from the aspects of process flow, grinding particle size, collectors and inhibitors.

Barite-calcite-fluorite type fluorite ore separation process flow

The composition of the barite-calcite-fluorite type fluorite ore is relatively complex. The current flotation process is mainly divided into two types: priority flotation and mixed flotation. The priority flotation method first suppresses barite and calcite to float. To select fluorite, the mixed flotation rule is to first mix and flotate barite and fluorite, and then suppress barite to flotate fluorite.

Grinding particle size of barite-calcite-fluorite type fluorite ore

The embedded particle size of barite-calcite-fluorite type fluorite ore is generally fine. In the grinding stage, as the particle size content below 0.074mm becomes higher and higher, the recovery rate of fluorite will also increase, but in the grinding stage, the recovery rate of fluorite will also increase. Too fine grinding particles will lead to a decrease in recovery rate. At this time, the adsorption of fine minerals is high, which reduces the selectivity of the agent.

Collectors and inhibitors for barite-calcite-fluorite type fluorite ores

In the flotation process of barite-calcite-fluorite type fluorite ore, the more commonly used collectors are oleic acid and oleate salts, sodium alkyl sulfate, naphthenic acid, oxidized paraffin soap, etc. In the selection of inhibitors, the more commonly used ones include water glass, sodium sulfate, etc.
